I am using a large maxijet powerhead for a DIY filter on my 10 gallon quarantine, as my most recent filter just broke, the problem is that there is so much flow that i don't want my fish to be spinning around in it, but i want to do it cheaply instead of getting a new filter. Any ways to reduce flow so the fish are okay? I'll be getting fish today, and they are african cichlids so they can take a lot of flow, i just want to make sure they are okay!!
