I have 9 lbs LR(will get more when money permits), 7 lbs base, and about 50 lbs of volcanic( I think, it will be removed with the addition of LR and base), with 2 damsels, and 5 blue legged hermits in a 60g long72x12x17. It's been running for a month. Should I remove my fluval 404 before or after I get more LR. It has a sponge, activated charcoal, and ceramic bio-media. When I get enough LR, it's gone. Should I dico it sooner(I keep hearing bad things about them, but I don't have enough LR) rather than later? Or is it helping me right now. I just want to do it right , without killing anything, and the books don't answer this one.
