Really confused about a couple things. First I did a water change in my 45 gallon tank after I notice I have no nitrite ammonia Is .25ppm which I read means 0 since it’s an ati test kit. My issue is the nitrate is light orange so in between 10-20ppm. Second day I checked and still hasn’t really come down. I have my protein skimmer going and the water is filled with micro bubbles as well. No skimate either. It’s a new skimmer so I think it’s still breaking in. I have some hermits, snails, a blenny and royal gramma. They all are eating and look healthy. I was going to get a couple clowns in the next day or so. I can’t tell if it’s safe to get a couple clowns or it might kill them. Any help would be great with the chemistry as well as protein skimmer. Thanks in advance.
