I started up my 110 gallon reef about 1 1/2 months ago after I had a crash about 1 yr ago. After my tank crashed about a year ago, I cleaned everything out and just let the rock cure naturally for about a year. Thats when I started everthing back up.
Everything was going well until I added some fish. The nitrate level is at about 80 now. I have made three 20% water changes over the last week and it still remains high. The ammonia, KH, PH, calcium, phosphate & temp. levels are fine. I also increased my protein skimmer to a more aggressive setting and added a catch bottle.
I was thinking about adding some nitrate asorbing materials and decided to go to the local fish store. I took a sample with me to make sure my test kits were working ok. The store tested the water and confirmed my results. Only the nitrate was high. He recommended a 50% water change and stated that what was going on in my tank was the new tank syndrome and was following the normal course until the bacteria built back up in my 100 lbs of rock in my tank. He said that the nitrate asorbing materials would not help much.
I have about 6 small fish, 8 coral, about 80 assorted snails, a starfish, one large worm and several feather worms in my tank now. I am afraid that if I do a 50% water change, that it will have negative results on everthing in my tank.
Any advise would be appreciated.
