My 75g has been running since Aug of last year. I'm experiencing a diatom bloom on half of my rocks. There's some on the right side rocks but the left half of the tank is worse. Sand bed is clean. My parameters as of last Thursday 28 jan are
Salinity: 1.021 (now at 1.026)
N03: 20 (same this week)
P04: .03
Alk 9 (now 10.5)
Mag: 1080 (now 1370)
Ca: 430
Ph: 8.3
I did a 25% water change on Sunday and do 20% every 2 weeks. Feed 3 times a day. Have a good cleanup crew and have 2 clowns, 1 purple dottyback, 1 one spot foxface, 1 diamond goby, 1 lawnmower blenny, 3 chromis, 1 coral beauty. My sump has two filter socks I change twice a week (switching to a roller this weekend), sea lettuce in the fuge section and biomedia. Trying to get this under control. Tested my rodi top off and it's showing 1. I dose cal and alk.
