The nice thing about making your own 3 part Comp 123 is the ability to alter recipe to accommodate higher/lower mag and ca. The system is derived by alk usage, which is Comp 2 of the Comp123 system, all others intended to dose equally. I eventually balanced out and found AF recommended recipe to be pretty close to dead on without a need to tweek the recipe. My alk remained very steady, my 120 gallon tank was using 230ml of each per day, 60+ Acropora colonies, all larger than softballs, some volleyball to basketball size, LOL![]()
Haha I'm confused, the nice part about it is that you can tweak it but you found out you didn't need to tweak it?
Glad it works for you though. Ever do an icp? Just curious.
Do you do water changes?
Thanks!
