I've had my puffers for about a week now. I just moved them into their own 40 gallon tank three days ago. I went to my local petco yesterday and get the saltwater api kits for nitrate and ammonia levels. I couldn't get the others because they were out. Anyways I've checked my levels for the two and my ammonia is perfect at 0ppm, but my nitrates are at 80ppm. I'll be doing 50% water changes every day for the next few days to lower that to a more acceptable levels, but do you have any tips to help keep them low enough? It's worth mentioning that I've just started slowly adding saltwater to the tank yesterday, to raise the salinity to proper brackish levels (it's currently at a specific gravity of 1.004), so I'm using the sw color chart, not the freshwater. I added two cups of saltwater to the tank so far. Also I've found several differing parameters so can you tell me what the correct water parameters are? Oh yeah the water temp is 80 f
