Hello! New to the salt water, new to the forums. Started about a month ago with a new-to-me 30gal. Loaded it with 30lbs of Argonite sand, 45lbs of live rock. Marineland C-220, Reef Octo 1000, CPR large refugium, a couple Hydor 455's, and a 100w heater. Since then, I have become addicted. I have already purchased a used 90 with overflow, and have started building a stand for it. I am now in the hunt for a 40g tank, or pre-made sump. I seem to not have permission to post onto the WTB thread, so any help would be appreciated! Thanks!
