We removed the filter entirely because we didn't know how to take the carbon out and the guy said, it's fine. When this is over in a few weeks, you'll be ready for a new filter anyway. I just did a test on the ammonia using a tetra strip because the lady at the other store told me what I bought, the API (which was recommended here, was useless, and that they use tetra in their tanks). So I used that and the ammonia was high under "stressful" stage. He had me dump triple the dose in though so maybe it locked it where it was? I poured a little bit of prime in there... didn't even bother to measure at this point, any amount will be beneficial to a tank that size and I'm hoping that helps detoxify it a little bit. I don't think I'm planning on waiting 10 days. Maybe 5 or 6 at max and then I will do a 50 percent water change and add the rest of the bottle. Some of the fish don't seem too happy at this heat--at all. I'm really confused what the lack of filter is for because he gaves us stuff that is supposed to boost the filter's performance. I can understand if you remove the filter so that the Ich spores don't get caught there and if you squeeze your filter into the next filter, you could be squeezing those spores into a treated tank. I'm just confused and have always come to the conclusion that my fish will eventually die. The black one with all the spots on its lips and face is very, very lethargic. Hiding at the bottom, staying all the way at the top. Not eating, etc. It's very depressing to leave my fish like this. I don't know what else to do. The other fish seemed pretty ok with the temp increase yesterday to 84 from 79 but now I think they are not happy being above that to about 85. My goal is eventually 86 but I don't know if they can handle it. Why would he give me this product instead of medication for the fish? It's called Microbe-Life Special Blend.
