I have a 55 gallon with 3 juvie carpintis about 2 inches, 1 bristlenose pleco and 6 cories. I have a fluval 406,penguin 350, and penguin 200 running with a koralia evo 800 powerhead. . I also have 5 crypts and some java fern in the tank. I have been reluctant to run the powerhead cause i thought it might be to much flow for the fish and the plants. N e 1 think this is overkill or to much current in the tank for the fish?
