Hi everyone! :;hi1 this would be my first post on fishlore but i have been getting my info from this website for a few months now, iv been in the market for a new tank to make a reef tank (eventually) and have found this one for sale locally and seams like a good deal, its 90 gallons and comes with basically every thing i need (sump/MH light/pumps/powerheads/live rock ext.) even the live stock! the problem is its coverd in that unpleasant looking green algae (even the blue tang has some on him). what im asking is if i get it will i be able to get it all off (the wall,sand and live rock) and will the blue tang be alright? im willing to put alot of cleaning time because the price is just to good to pass up. also do you think this tank would be a good tank for my first reef tank?
