Ok so I am doing a fishless cycle in my new 37 gallon FOWLR tank. I have aragonite sand and dry live rock in the tank, and 4 days ago I added a bottle of Bio-Spira. I got pure ammonia (Ace Hardware janitorial brand as suggested) and started dosing. Day one I dosed it to 4 ppm. The next day the ammonia had dropped to 2 ppm and nitrites were 4ppm plus. Day 2 ammonia was 0, nitrites still high, and nitrates were about 10 ppm. I dosed ammonia to 2 ppm. On Day 3 the ammonia was 0, nitrites high, nitrates about 20 ppm. I again dosed ammonia to 2 ppm. Today is day 4. Ammonia is 0, nitrites haven’t budged and are still very high, nitrates 10 ppm. I have read on these forums that people suggest keeping ammonia levels at 2 ppm or so, so that the bacteria have a good source. Others say to give the ammonia a break if the nitrites are really high. So which is it? The man at my LFS said to dose until day 7 and then call it quits and keep testing. So what do you guys say? Should I keep dosing everyday, or stop at any point? I’m hoping the nitrites will start to drop soon. Any tips? I know this part takes some patience as well. Thanks! Also salinity is 1.023, temp is 80. pH is between 8-8.2
