In this episode of Reefing Radio, Chris and Gareth strip reef keeping back to basics and ask a simple question: what do you genuinely need to run a successful reef tank? From ATOs, flow and temperature control to test kits, live rock and backup equipment, we work through the gear and practices we think are truly essential. Along the way, we also challenge some of the hobby's biggest assumptions, including whether you really need to dip every coral and if clean-up crews are as important as they're made out to be. Whether you're setting up your very first reef tank or rethinking how you run an established system, this episode is packed with practical advice, personal experiences, and a few opinions that might spark some debate. As always, we'd love to hear what you think is essential... and what you'd happily leave out.

In this episode of Reefing Radio, Chris, James, and Gareth have a catch-up after a run of guest episodes. We chat about what's been happening in our own tanks, the lessons we've learned over the past few months, and how our approach to reefing is starting to change. Gareth shares the plans for his brand new custom-built reef, explaining why he's finally replacing his ageing Red Sea tank, the thinking behind his bespoke wavebox design, and how he's aiming for a simpler, more natural-looking display with fewer coral species and larger groups of fish. Chris talks through the recent heatwave, the challenges it's created for his SPS system, and why he's seriously considering moving away from an SPS-dominated tank in favour of something that's better suited to his lifestyle. James gives an update on his thriving soft coral reef, including how higher temperatures unexpectedly accelerated coral growth, why he's embraced a more relaxed approach to reef keeping, and what happens when you simply let soft corals do their thing.

In this episode of Reefing Radio, we're joined by Mark Bindefeld from MB Aquariums to explore the world of professional aquarium maintenance. Mark has built a successful business maintaining everything from tropical aquariums and reef tanks to large commercial displays, giving us a fascinating insight into a side of the hobby that most reef keepers never see. We discuss what it's like looking after other people's aquariums, the types of clients who use professional maintenance services, and the biggest challenges of turning a passion for fishkeeping into a full-time career. Mark shares stories from the field, from emergency call-outs and holiday cover to rescuing neglected systems and maintaining high-end reef tanks. If you've ever wondered what it's like to maintain reef tanks for a living, considered hiring a professional to look after your aquarium, or even dreamed of turning your own hobby into a career, this episode offers a behind-the-scenes look at one of the most interesting professions in the reefing hobby.

In this episode of Reefing Radio, we’re joined by Courtney Keeps — a hobbyist known for his beautifully designed macroalgae reef tanks, natural daylight-style aesthetics, and thoughtful approach to aquarium design. Courtney shares his journey from freshwater aquascaping into the reefing world, including how planted tank design principles, gardening, and a love of natural aesthetics have shaped the way he approaches marine aquariums. We discuss what the reefing hobby can learn from aquascaping — from intentional layouts and repetition to colour placement, depth, restraint, and designing tanks that feel cohesive rather than cluttered. The conversation also dives deep into macroalgae systems: how to grow them successfully, nutrient management, lighting, dealing with nuisance algae, species that thrive (or crash), and why macroalgae tanks behave very differently from traditional coral-dominated reefs. Along the way, we talk about natural seawater, freshwater influences on reefing, blackwater tanks, nano systems, and the challenge of balancing aesthetics with practicality. Courtney also walks us through his latest shallow lagoon-style setup — including the philosophy behind the design, custom-painted cabinetry, canister filtration, and why the overall presentation of an aquarium matters just as much as what’s inside the glass.

In this episode, Chris, James, and Gareth are joined by Brian Schaff, CEO of Tropical Marine Centre (TMC), the UK’s leading suppliers of marine livestock and aquarium equipment. We take a closer look at how marine livestock makes its way from the ocean to our tanks, with Brian walking us through the central role TMC plays in supplying the UK reefing hobby. Along the way, we get into wild vs captive breeding, the positive impact the hobby has on local communities, and why the trade is often more responsible and sustainable than it’s given credit for. We also touch on fish ranching, as well as the complexities around topics like biopiracy. If you’ve ever wondered where your fish and corals come from — and what happens before they reach your local fish store — this is a detailed look inside one of the UK’s most important reefing operations. We’ve also filmed a separate video tour of TMC with Brian to accompany this episode, so keep an eye out for that coming soon.

In this episode of Reefing Radio, we’re back to a classic catch-up after a run of guest episodes — just the three of us talking through what’s been going on in our tanks lately. James shares updates on his soft coral system, including new additions, how it’s starting to fill out, and his approach to keeping things simple with minimal equipment and intervention. We also touch on sourcing more unusual corals and how his tank is evolving visually as it grows in. Gareth talks through his new shallow reef build, including the DIY wavebox that’s been getting a lot of attention, the challenges of modifying the tank, and his plans for a more natural-looking setup with fewer coral types grown out over time. We also get into stocking ideas, from groups of fish to future plans for clowns and anemones. Chris rounds things out with updates across his tanks, including dealing with white spot using tank transfer method, changes to dosing, and setting up a mantis shrimp pico tank. We also reflect on how our tanks are starting to look more alike, and whether that’s just the result of reefing together. 👉 Follow us on Instagram: @reefing_radio📘 Find us on Facebook: Reefing Radio💬 Drop us an email at: [email protected]🎧 Subscribe to hear more reefing chat every week

In this episode of Reefing Radio, we continue our conversation with Dr Jamie Craggs to explore one of the most exciting frontiers in the reefing hobby: spawning corals at home. In the previous episode, we unpacked Jamie’s work and the growing importance of coral reproduction for reef restoration. This time, we bring it back to the hobbyist level — asking a simple but powerful question: can you actually spawn corals in your own tank? We dive into the practical realities of coral spawning, from understanding reproductive strategies and seasonal triggers to what really matters in a home setup. How important are temperature swings, lighting cycles, and moon phases? What can you get away with — and what actually makes the difference? We also explore the tools that can help you get started, including the coral spawning database developed by researchers at Newcastle University — to start predicting when your corals might spawn. The conversation then moves into what happens next: from catching spawning events to raising larvae, settlement challenges, and why this is where things get genuinely difficult. Along the way, we touch on hybridisation, sustainability, and what this could mean for the future of the hobby. If you’ve ever wondered whether coral spawning is something only labs can achieve — or something you might realistically attempt yourself — this episode gives you a clear, grounded starting point. 👉 Follow us on Instagram: ⁠⁠⁠@reefing_radio⁠⁠⁠ 📘 Find us on Facebook: ⁠⁠Reefing Radio⁠⁠ 💬 Got feedback or questions?

First things first — apologies for the gap since our last episode! Life got in the way for a few weeks, but we're back on schedule now and we've got a cracking episode to make up for it. In this episode, Chris, James, and Gareth are joined by Dr. Jamie Craggs — marine biologist, coral researcher, and the scientist who changed everything we thought we knew about spawning coral in captivity. Jamie is the principal aquarium curator at the Horniman Museum and Gardens in London and the lead scientist behind Project Coral. He's also co-founder of Coral Spawning International, which is deploying spawning research globally in support of reef restoration and local communities — with over 100 systems now operating across 19 countries. This is Part 1 of a two-part conversation. Here, we focus on the big picture and Jamie's story: why the world's coral reefs are in such serious trouble, from climate-driven bleaching to blast fishing, and what the stakes really are for biodiversity, coastal communities, and the future of the hobby. Jamie takes us through his journey from hobbyist to researcher, explaining how he made the leap from jellyfish to corals and achieved the world's first predicted coral spawning event in a fully closed system — and what it took to scale that breakthrough into a global restoration tool. We also get into coral biology along the way, covering the difference between brooders and broadcast spawners and why good husbandry is a more powerful scientific tool than it's often given credit for. Jamie also highlights the Great Reef Census as a brilliant way for hobbyists and ocean lovers to contribute to real coral reef research from anywhere in the world — link here. In Part 2, we get practical. Jamie will be back to walk us through what coral spawning at home actually looks like — and whether it might be more achievable than you'd think.

In this episode, Chris, Gareth, and James are joined by Jake — better known as Jake EC on Ultimate Reef — to explore the weird, wonderful, and often-overlooked side of reef keeping. Jake is known for his natural-looking mixed reefs and an extraordinary collection of unusual fish and invertebrates, from shrimp, starfish, and cucumbers to nano fish, symbiotic pairings, and rare oddities you rarely see in home aquariums. We dig into how and why he stocks his tanks the way he does, focusing on behaviour, interaction, and realism rather than trends or hype. We talk about keeping unusual livestock successfully, pairing and grouping fish and inverts, sourcing rare species through strong retailer relationships, and what it takes to run a diverse, invert-heavy reef long term. Along the way, there’s plenty of discussion around risk, responsibility, learning through experience, and why curiosity still matters in the hobby. 👉 Follow us on Instagram: ⁠⁠⁠⁠⁠⁠⁠@reefing_radio⁠⁠⁠⁠⁠⁠⁠📘 Find us on Facebook: ⁠⁠⁠⁠⁠⁠⁠Reefing Radio⁠⁠⁠⁠⁠⁠⁠💬 Got feedback or questions?

New Year Reefing Resolutions We kick off 2026 with a reefing catch-up and some New Year’s resolutions. We talk about what got done over Christmas, what got neglected, and what we’re realistically trying to do better this year — from water-change routines and testing discipline to spending less money (we’ll see). There’s plenty of tank chat too: James’ plans for a softer, sponge-led system (and resisting the SPS temptation), Gareth’s rock-solid routines and why he’s officially done buying livestock, and Chris resetting his SPS cube with live rock, new flow, and a hard push for stability after a rough year. We also dig into skimmers vs refugiums, pH struggles in winter, salt choices, dosing philosophies, and whether stability really does just come with time. A relaxed start to the year, plenty of opinions, and a look ahead at what Reefing Radio has lined up for 2026. 👉 Follow us on Instagram: ⁠⁠⁠⁠⁠⁠@reefing_radio⁠⁠⁠⁠⁠⁠ 📘 Find us on Facebook: ⁠⁠⁠⁠⁠⁠Reefing Radio⁠⁠⁠⁠⁠⁠ 💬 Got feedback or questions?

Raise the Reef: Inside the World of a High-End LPS Retailer Chris, Gareth, and James are joined by Ash from Raise the Reef, a UK coral retailer specialising in vibrant, high-end LPS, with a particular passion for torches and unusual pieces. We dig into Ash’s journey from garage-based fragging to opening a physical store, and what it’s like running a coral business alongside a full-time job. Ash shares how he selects corals in person, grows out and colours up high-end LPS, and why feeding, nutrients, and flow matter far more than most people realise. Along the way, we talk about the realities of coral retail — from sourcing and growing corals, to supporting customers, building community, and balancing livestock care with the commercial side of the hobby. There’s also plenty of discussion around feeding, nutrients, flow, and what it actually takes to keep LPS thriving long-term. 🔗 Check out Raise the Reef at ⁠raisethereef.co.uk⁠ and on Facebook. 👉 Follow us on Instagram: ⁠⁠⁠⁠⁠⁠@reefing_radio⁠⁠⁠⁠⁠⁠ 📘 Find us on Facebook: ⁠⁠⁠⁠⁠⁠Reefing Radio⁠⁠⁠⁠⁠⁠ 💬 Got feedback or questions?

Reefing Radio – “How Many Fish Is Too Many Fish?” This episode is all about adding fish, stocking sensibly, and working out when a tank has reached its limit. We compare approaches, talk through what actually matters when choosing new additions, and look at how aggression, space, nutrients and behaviour shape whether a fish will work long-term. We also have a catch up on our tanks: James’ softie system with booming yellow sponges and neat lines of hair algae, Gareth’s bubble coral that turned out to be riddled with boring sponge, and Chris’ UNS 90LA tank transfer — plus the calcium precipitation event that left his SPS cube coated in white dust. 👉 Follow us on Instagram: ⁠⁠⁠⁠⁠@reefing_radio⁠⁠⁠⁠⁠ 📘 Find us on Facebook: ⁠⁠⁠⁠⁠Reefing Radio⁠⁠⁠⁠⁠ 💬 Got feedback or questions?

After a longer-than-planned break (life got in the way!), the Reefing Radio trio are back behind the mics. In this episode, Chris, James and Gareth catch up on everything that’s been happening in their tanks — from Gareth’s elegance coral rollercoaster and growing Pectinia obsession, to James’ mangrove tank and one extremely naughty hogfish, to Chris’ shut down of the nano lagoon and build-out of the new UNS 90LA. We also dive into a brilliant listener question on “marginal gains” in reefing. Are those ultra-precise tweaks actually worth the effort? Or are we all guilty of overthinking it? Expect calibration chat, food-washing scepticism, and a surprisingly sensible framework for working out what actually matters. To finish, we share the animals we wish we could keep but realistically can’t — from clams and Moorish idols to the fish Chris still dreams of one day finding a way to make work. A relaxed, honest, reef-nerdy episode — thanks for sticking with us, and enjoy! 👉 Follow us on Instagram: @reefing_radio 📘 Find us on Facebook: Reefing Radio 💬 Got feedback or questions?
