My phsophate is 0, and my nitrate is 5. And i feed frozen everyday, and i have 5 fish in a 36 gallons with 18 gallon sump. I do biweekly water changes, and i was wondering how do i keep my phosphate from bottoming out to 0? I turned my skimmer off yesterday at night and fed AB+ for for the first time. And turned the skinmer back on in the morning. And my phosphate got back to 0.04 from 0. But isnt turning off and on the skimmer gives me PH swings? My ph is 7.97 in the morning and 7.76 at night...

. sorry to side-track this thread. carry on
