Hey guys, this weekend I tested my water (I usually test weekly unless something appears out of the ordinary), and found the nitrates had skyrocketed. At least 160 ppm according to my test. I recently added quite a few feeder shrimp into my breeder net, I'm wondering if that may have done it. SO STUPID. I've done several water changes (about ten gallons a day, this is a system with about 50 gallons total) for the last 3 days. I have the nitrates down to somewhere between 60 to 80 ppm. There has been 0 ammonia, no pH shift, no nitrites. Just a LOT of nitrates. Amazingly, the cuttles don't seem affected at all. No behavioral changes. I realize they produce a lot of waste. I also found a dead turbo snail on saturday, so its possible that was the source initially. I'll be keeping my feeders in a separate tank from now on and watching everything like a hawk. Curious what others' nitrate levels hover at? Before this mine were at around 40, but its possible that the combined waste from 4 now larger cuttles is doing it. Skimmer is working well, pulling skimmate, so it doesn't seem to be that. I usually do about a 25% change weekly.
