Hey, I'm a saltwater beginner I have a 40 gallon breeder with 20 gallon long sump, please don't judge but I am finishing my cycle with fish in (2 clowns) per my LFS recommendation after having crazy high nitrites and nitrates (like 200ppm). After doing a 90% water change and then probably 98% water change to get my parameters down I got them down to 1ppm nitrites per api test kit and 4.8ppm nitrates per Hanna checker, then did a 10 gallon water change and checked my nitrites before I went and got fish, but didn't check nitrates, that was on the 8/25, checked my parameters daily yesterday (8/28) my nitrites were .25ppm nitrites and my nitrares were 3.6ppm per Hanna checker, now today (8/29) my nitrites were still .25ppm but now my nitrates... 0ppm per Hanna checker and red sea, how could that be? I do have a small little bit of algae on my rock but don't think it's enough to suck up all the nitrates...
