Andrew McFadden said:Did you double check the test? Is the kit outdated? I can't believe the numbers are that high and those fish are looking good and kicking. I'd do at least a 75% water change if it still test that high for now. Then work on getting rid of some of the fish to lower the bio load. When you replace the cartridge do you do both filters at the same time? And how do you wash them?
Yea I usually do both filters at the same time do you think I should them at different times and I'll do another test to see what's up also I'll do a big water change. I'm also about to get rid of the oscars I've had them for a long while and there getting pretty big. You said something about washing the filters should I do that cause I didn't want to keep using the same filters it really sounds the same as new ones if I'm washing it?
