Also a good point, I’ve helped jf out a couple times at his place and talked with quite a few other coral farmers. Him and others whose entire livelihood depends on coral growth and coloration, yet they all tend to keep all at ~8.
If higher alk were truly advantageous and truly made corals grow faster, would these coral farms not all be running 12?
I feel like this high alkalinity method that I often see with newer/less experienced reefers is fed to them through some sort of product/advertising and is never really utilized by the leads in the industry. I have yet to come across anyone of note running an all that high, despite running other “iffy” methods such as monthly chemiclean dosing.
