Reefing Radio – “Keeping It Stable” pt. 2
Chris, Gareth, and James return to wrap up our deep dive into reef tank stability — this time we cover the parameters and approaches we didn’t get to last week. From magnesium mysteries to nutrient balance, trace elements, and the pros and cons of different dosing strategies, it’s a packed episode.
We cover: Magnesium & calcium – does magnesium really matter, and why do some tanks never consume it? Alk/Ca balance – James’ strong views on why the two need to be paired Trace elements & ICPs – useful tool, false reassurance, or just a money pit? Nutrient stability – balancing nitrates & phosphates, high vs low nutrient systems, and how lighting ties in Dosing approaches revisited – All-for-Reef, two-part, DIY mixes, and kalkwasser (including slurry and reactors) Quick-fire round – the one parameter we’d peg forever, and the most overrated one in reefing
We also announced the winner of our £50 Prestige Reef gift card giveaway – congratulations to the winner!
🎧 Tune in for one of our longest episodes yet, full of debate, confessions, and a few surprising takes on what really matters in reef stability.

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.
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.
We recently visited Tropical Marine Centre — the UK’s largest importer of marine fish and coral — for an exclusive behind-the-scenes tour with CEO Brian Schaff.In Part 1 of this series, Brian takes us through TMC’s fish systems, quarantine and acclimation processes, animal care philosophy, and the logistics involved in handling thousands of marine fish each year.We also discuss fish health, decompression, captive breeding, UV sterilisation, feeding systems, and how TMC approaches marine livestock care at scale.Huge thanks to Brian and the whole team at TMC for taking the time to show us around.Part 2 coming soon.Don't miss our full sit-down interview with Brian Schaff discussing the reefing industry, supply chains, sustainability, and how the marine trade works.
