Hi guys over the weekend I brought a fluval spec v I saw it at my local Lfs and couldn't resist! I know the stock light isn't the best so I've gone with driftwood and moss,I'm a little concerned about the filter,the out flow is really good but it doesn't seem to be pulling much debris down though the sponge.Is this a problem or am I worrying too much? How do you guys find the filter set up?
