I have a 10 gallon nano that only has one fish in it, so I don’t feed too much in the system. As a result my nitrates are at 0, which I know isn’t great for corals. I’m trying to get them around 4-5 and I wanted to know from those of you who dose nitrates what you preferred to use. I was thinking of just using phyto feast concentrate. I have a lot of corals in the tank so I want to make sure they all get plenty of food. Thanks!
