Hi all, I have just bought a new nac7 protein skimmer for my tank, it came without any instructions, so iv assembled it and it looks beautiful in comparison to my crappy v2 skim which can go in the bin!!! Has anybody got any advice on the nac7's also how far up the cup to have the bubbles? Also there is a drain off hose is it wise not to use this?? Thanks for the help
