During a Diatoms outbreak in a new 75 gallon tank 3 months old. My PH dropped to low 7s. I did a big water change 20% after water was getting extremely cloudy and added some PH buffer to help increase the PH back and moved pumps to surface to allow more air into the system. I did purchase a Media Reactor and added some BRS GFO to help eliminate phosphates on the water. I do use a 4 stage RODI for water. My blue tang and coral beauty today was covered. No other fish seems to be infected as of yet. I do have a few coral and a lot of rock so catching and removing is NOT an option. I do not own a QT tank sadly. My six line wrasse is eating some of the ich off them. But it’s very very slow. Can anyone give me products or assist with anything I can do to control this and help remove. Once again it must be Reef safe and I don’t own a QT tank. So copper isn’t an option. Thank you
