Red Sea Recipe For Mixed Reef 11.5 DKH?!?!

demariners · 04/14/2019, 11:49 PM

Anyone else skeptical on the Red Sea receipt for mixed reef. I think that DkH number is a bit high? Am I missed something here? I am afraid to attempt for such a high number and stick to my 8-10? Anyone had success with 11.5?

If your nutrient levels are higher you can get away with elevated alkalinity and that can help accelerate growth..
But most recommend against that now and shoot for 8-9dkh or so as lower nutrient levels are quite common to achieve/maintain now.

11+ dkh is so old school. Unless you’re doing everything old school. I’d avoid going there with that one parameter regardless of what Red Sea suggests. I’d love to see an honest representation of people who carbon dose, run low to ULNS like the Red Sea program is designed, but also run 11-12 dkh and have primarily all acropora, and for an extended time to allow frags to become colonies (the system has been out for plenty long enough). I’m guessing there may be one to two responders at most. But mostly crickets. Reason being, the Red Sea system at its heart is designed for a mixed/softy dominant tank. Where alk that high is less likely to hurt anything.

I have mostly softies but a few SPS and clams as well. I would presume that the high Alk is a no no. I will stick to around 8.5 but the rest of those parameters look on par.

As others have pointed out 8.5-9.5 is good for most applications
What I might suggest is look for stability, corals love stability, and hate change, so pick your number and keep it there. Applies to all parameters but especially ALK

10-11 unless you're doing an outdated ULNS system.
