So I'm running GFO right now in my 40gallon mix reef tank, and I'm still getting this brown algae film in my glass that just wont go away. Sometimes it last 3 days without appearing and then itll come back. I came across this chemical (Phosphate Rx) not sure if I should try it. My Phosphate level is at .092ppm lowest Ive seen is .069ppm with the GFO. Just tryin to see if anyone has used this chemical.
Also, if I do use it should i stop the GFO from working together with it as well. Please let me know thank you!!!
