I just bought a new Penguin 150 for my soon to be 10 gallon planted tank. I was wondering if the filter would still run fine if I took the carbon out of the filter pad that came with it (because carbon can mess up plants) then behind where the pad slides in put one foam filter insert, then a bag of ceramic filter rings then another sponge. I'll add a link to the pics hopefully it will work and give you a better idea as to what I mean.
