That is the main problem, I can't figure out how to save the tank, I have done everything I can think of. And now it is down to tear the whole bloody thing apart. As you know I would have to totally empty the tank, down to bare glass and take it off the stand just to work on the skimmer. If I have to go that far, I might as well set up a new tank where I would have room to work.
I have tried for months to get the chemisty in order, and it is not working. so now I think it is something in how the sump was set up. Maybe I have the water going thru to fast. I don't know. But something isn't right. I should not keep have nitrates of over 100. I know I don't over feed the fish. The water is good. I can't get my alk up to a safe level. I just think the only way to fix it at this point is to scrap it.
