I saw your website listing bulk head fitting kits. B4 I order, can you recommend the hole size and locations for a 75 gallon tank. I am setting up a reef tank and do not want to use a hang on pre-filter. I am concerned that If I do not drill the holes in the right place it could weaken the tank and overflow the sump if power failure. I have been told it is standard to drill for schedule 40 piping. What would you recommend for adequate water flow and what turn-key kits can I buy from you.

Hi, I was looking at your insulated tanks and I really am looking for the one with the front window pain. I am just curious can you put and over flow in them and a stand underneath or do they usually have bulkheads built into the sides and you can plumb it that way? Also how much would it be for a 10′X8′X30in with a window just in the front, black tank with filtration and lighting.

Our club would like to purchase 4 hard shell tanks (blue) 48″ dia 30″ high. You don’t have any listed on your web. I have purchased these thanks before from you. Do you have any used tanks aorund that size. If not please quote price for 4 new tanks 48″.
