I have a juwel rekord 60 and am wondering whether I could add a 2nd filter to boost up the flow for my plants. I have an elite mini filter somewhere that I could just fill with filter wool and run as a basic powerhead if anyone thinks that could work? If not does anyone know of a better filter suggestion, I don't really want to go to the effort of ripping out the installed juwel box. I have dwarf puffers in this tank so don't realy want to go too OTT with the flow, would adding more circulation help stop hair algae?
