Help! I'm at the end of my rope! We have had major diatom outbreak for about 7 months now. We have tried everything recommended from frequent water changes, chemicals/additives, less food, less light time, suctioning off layer of sand, cleaning filters and tank and replaced the RO
filters. Our tank is 75 gal
, refugium, filter, skimmer and 2 wave makers. There's 1 tang, 1 chromis, 4 cardinals, 3 corals, live rock, 3 snails, 4 peppermint shrimp and some bristle worms. All parameters are good and always are. Any suggestions are greatly appreciated.
