Calireefer92 · Feb 23, 2020

Hey reefers need help here. So I did some testing today my calcium is at 431 alkalinity is at 8.6. My question is should I raise the alkalinity a little bit? I have the Red Sea abc liquid foundation so if I need to raise it how much would I dos I have a 112 gallon tank much help would be appropriate thanks guys

I run my ALK a shade lower than that in my SPS dominant tank. So I don’t see an urgent need to increase your ALK. Some people believe that one gets faster coral growth with moderate nutrient levels with higher ALK levels.

From my poking around, you would increase your ALK by 1 by adding about 40 ml of additive. But I would dose less and check the increase before taking these figures as reliable.

IMHO, your Calcium and Alkalinity are right smack in the middle of spot-on. If you are dosing now, keep doing what you are doing. If not, you probably don't need to yet.

I have a lps/softies and I usually don’t test because I do weekly water charges but I’ve been cutting back on that to every 3 weeks so I decided to test so I was just wondering if I should raise it
