Hi everyone, I decided to use tetra safestart (used the big bottle of tetra safestart plus) for my tank because I've read about it getting good results. I ended up getting a 29 gallon aquarium, it has tons of live plants, and I decided on some ember tetras because they're probably my favorite and the lady at my LFS told me they're pretty hardy, etc. I've read mixed things about their hardiness since then, though. Anywho, I have 6 of them in the tank and my cycling process seems to be well underway. I'm just concerned because my nitrates seem to be creeping up to the 10-20ppm range. I know the instructions for safestart say not to do any water change for 2 weeks, but should I be worried about the nitrates getting any higher? They seem to be increasing by 5-10 per day so soon it'll be in the red I think. Also, would it be ok to add 6 more ember tetras, or not yet? They seem to be doing well, but 3 or 4 keep schooling while the others are hiding under leaves or behind a rock, so I wonder if a bigger school might make them all feel better/less stressed. Here's a picture of my most recent test (interestingly, pH has increased a bit from where it has been...) -- sorry if I did this wrong, first time trying to upload a picture IMG_6103 by cappuccino91 posted Apr 10, 2018 at 12:46 AM Here are all of my parameters since the beginning: Day 0: water before safestart (forget if this was before or after adding prime... I'll have to test my untreated tap water again), no fish yet: pH 8.0, ammonia 0.25ppm, nitrite 0ppm, nitrate 0ppm. Day 1, before adding TSS and fish: pH 7.8, ammonia 0.25ppm, nitrite 0ppm, nitrate 0ppm. Day 2, 24 hours after TSS + fish: pH 8.0, ammonia 0.25ppm, nitrite 0ppm, nitrate 5ppm Day 3: pH 7.8, ammonia 0.25-0.5ppm?, nitrite 0ppm, nitrate 10ppm Day 4 (today): pH 8.2?, ammonia 0.25-0.5ppm?, nitrite 0ppm, nitrate 10-20ppm? (hard to tell exactly) I know the cycle probably isn't complete yet because the ammonia reading is greater than 0ppm, but I don't want to leave my fish in water that has too many nitrates. Should I do a water change? Add more plants? I'm getting a bucket of water ready (treating it with prime) to use tomorrow if need be so it will have been sitting around for 24 hours before use. Thanks for any advice!
