I moved over 2 months ago and with me was my 75 gallon rr tank. I have around 100 lbs of rock, mostly soft coarls, also 3 fish. Im running a sump with rubble. Im also running a phosban reactor with phoslock (changed weekly) for over 2 months now and I still have algae covering all my glass within 3 days to the point its a good film cover! Now it always says i have a hint of phosphates I dont know what else to do phoslock gets expensive everyweek for that long and I cant figure out where it is leaching? ask me any ? I will answer just please help thanks!
