Thank you I do have the master test kit I've been using. Also my fish store gave me a sponge from one if there tanks but I still can't get it to cycle. I've been putting in fish food. I'm at my wits end. I has to move all the fish to my 3 gallon tank so I didn't lose them all. So far 4 dead out if 11. Might have another one headed out as well. I'm so stressed. I've also been using prime.
