I have a 110 gal tank, wet/dry w/bioballs, skimmer, uv ster, 3 powerheads in main tank. I use aquarium pharm tap water filter for my water changes and top off. My ph is 8.2, amm is 0, nitrites are .1, nitrates are 75, phosphates are 2 and cal is 450. I only feed every other day with fresh food I blend and freeze myself. I also have a red and black algea bloom in my sand due to phos I am guessing. Well, I have been using kent phos remover for 2 days and will be swapping it for new bag in the sump today as per instrutions on the bottle. No change in phos though. Nitrates I constantly use nitrate sponge and still I have nitrates. I do 25% water change about every 2-3 weeks with IO salt mix. My coralline algea on my rocks is rapidly disappearing, my fish are going through ick and I just added a red slime algea remover powder 2 days at the same time I put in the phos remover and now my skimmer for the first time is going haywire and filling a whole gallon of clear water i about 5 min. It did it 5 times so yesterday I had to shut it down after adjusting it to the lowest level it stil kept filling. It is foaming like crazy. Oh I also have 100 lbs of LR. Please help before I just tear it all down and chuck it in the garbage. I did do a water change of 25 gal a few days ago and it didn't help. Where is all these sh** problems coming from? Oh the crazy LFS did have me dump some phos remover powder straight into the sump 2 months ago and now I know that could be seeping phos into the tank so there I think I may be out of luck, no? Please help!!!!!
