I don?t think ai primes are that strong

Honestly if your are testing correct then your nutrients are too low
You don?t want zero nitrates and phosphates

It?s debatable but most people shoot from 2-10 on nitrates and .02-.10 on phosphates


I would start with taking the Gfo offline
Also do you have a hob protein skimmer. I would add one if you don?t have one. It helps increase ph a little

Before your take Gfo offline. You might want to get another test kit for phosphates and nitrate. API isn?t great test kit. They might not actually be zero

Also are you dosing.

Also how often do you test. Do you test before and after water change. How big was water change again

I use Red Sea for nitrate and Milwaukee digital for phosphates

The digital is a little expensive but I can?t tell the difference on salifert and Red Sea phosphates test kits so I went with digital. On the nitrates it?s hard to tell color too but the digital isn?t that accurate in nitrates anyway imo

Also I would start testing alk every other day. Alk being stable is the most important aspect for sps

Also 25 percent water change is very big imo you run the risk of the water change water being a lot different levels of your tank water with such a big change. I understand it?s only 5 gallons. So be sure to test the wAter change water to make sure levels are close to tank water
