I've had my 2 goldfish for around a month now one rescue, the other unexpected. They are still in a 10 gallon tank looking to upgrade and separate both of them later on. . Anyways my water levels are High Range pH: 7.4 Ammonia: 0 Nitrite: 5 Nitrate: 5 . I believe my nitrite is high due to overfeeding so imma cut down the food, as well as over stocking( they are still relatively small but growing). . I was wondering if a water change or partial water change will do the trick and add some seachem prime to it. Will that do the trick?
