Hey guys, cycling my first sw and the nitrates won't seem to go away! Using 100% live rock and sand from a mature lfs aquarium they were getting rid of. Been cycling for about 2 weeks now and my levels are pH- 8.0 Ammonia- .25 Nitrites-0 Nitrates-80 So after a few days of these results I added a dose of prime to the water and was wondering if I should do a water change to get rid of the nitrates. Am. Cycled yet? Thanks!
