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.
