Well first let me say hello and I need help/advice. I've had freshwater tanks on and off for the last 20 years. I've always had great sucess with my freshwater and decided to try saltwater. I recently purchase a 90 gal. tank, filter, light sand live rock, the whole works from my local pet store. I've used this same store for the last 20 years and never had a problem with my freshwater needs. Even thought this store appears to know what their doing I feel screwed. I was told I'd never have to do another water change and the saltwater was less maintance. I found out different. I set my tank up exactly as I was told to by the store and it took 4 months before I could put fish in it. I'm still having problems with nitrates. I finally got the tank to spike about 2 months ago but the owner of the fish store told me to give the tank more time and the nitrates would go down. They never did and she told me that we could turn it into a freshwater tank. I told her **** no!!! I spent almost $3 thousand and I was not having a fresh waqter tank. I've got about 60 pounds of rocks and my sand looks like . When I put the live rock in the tank she told me to take the rock directly out of the box place it and all the crumbs into my trank. I later found out we should have done different. After three months of no success she came to my office and reached into my tank bare handed and took my live rock out side and "washed" it off with a garden house. She then put it back into the tank, she said this would help it to bring the nitrates down and get any loose particles off the rocks. I'm telling you I'm so ****ed I can't see straight. So I've washed my hands of this local pet store and will not walk in there again. So I'm going to need as much help from you guys as possible.
