Dear Leroy:
I have sent you some PICS of my first coral farming rack. The bottom two tanks are plywood tanks. The body fill I used is called fiberstrand and it is a waterproof filler. The paint is Sherwin Williams tank clad paint.

The owner of the store wouldn't sell it to me at first because he said (it will only work on tanks 20,000 gallons or larger) after a few phone calls I got him to sell it to me. The tank clad comes with 4 gals of paint and one gallon of hardener (4 TO 1 MIX) for approximately $175.00. The paint is fairly thin and I found it easy to paint with a foam brush and then just throw everything away rather than try to clean a regular brush.

The top 3 tanks on the unit are clear Rubbermaid storage bins. I thought these would make good gravel bowls for cuttings because they are very inexpensive and easy to plumb with PVC pipe (use a male and female union with O rings. I have also been using the plastic shoe boxes for rotifers green water & brine shrimp.

Some mistakes I made that are easy to avoid are;

1.) Make the stand at least 49 inches wide because a 48 inch bulb with end caps don't fit in a 48 in opening.
2.)Use large pluming for over flows it can be restricted if need be but you cant make it bigger.( flexible sump pump hose works great for overflows)
3.) Make sure all electrical outlets can't get wet use drip loops and mount power strips up and to the side of you tanks I will enclose a PIC of why.
4.) Leave enough room around the tank so that you can reach around the back to fix things)
