First marine tank

[bmckee727]

Let me start at I found 29 biocube used. Added 3gal vinegar and rest water, ran it a few days,scraped off all coraline, emptied completely, and have been doing 100% water changes last couple weeks. Either next weekend or one after that I plan on taking it out and taking the hose to it to try to blast out anything left under false floor and bottom of rest of chambers. I need a new ballast for attinic lighting but this being intended for a FOWLR setup are the Attinics needed right off the bat? Also intake fan is really lagging and loud at times, do you recommend me using one out of an old computer I have? Should I cut the false floor out of first chamber so it doesn't trap stuff to rot? I will start with these but have many more to come, thanks!
