My first tank had diatoms for 2 weeks and gone! This latest 68 g with sump is going on 6 weeks of diatoms and now over the last 2 weeks showing signs of Cyanobacteria bacteria. I added a 3rd smaller blower pointing to the area where the red started materializing is and it's not really helping. The diatoms and now cyno are mingling together and spreading! I want to just remove all my sand!! But I have lots of sand snails and pistol/goby combo not to mention my fire fish is burrowing in the sand..All my water parameters are good. Phosphate is 0 on hanna checker. All coral and fish are thriving! I don't know what to do without using additives and I don't want t do that.
I read 3 days of darkness is helpful.. Is that no lights? or no lights with a cover? As in total blackness? I can't bare the thought of putting FISH into blackness! If it just a matter of no overhead lighting ( My 2 kessels))I would try that..
Any thought? I'm so sick of looking at the nasty looking sand.. After a WC and a good vacuuming its great till the next day!
btw...I have removed the layer of nasty sand but it still appears!
