Makes it a bit easier to scuff up and coat with epoxy. I know it is toxic, as my dog wont come near the water in the tank. I had a 30 gallon polypropylene barrel collecting water off the canopy not much more than 3 feet away, still out of direct sunlight. And it was full of Algae and all stages of skeeter development shocked


JKB, that's correct, you didn't mention plastic tanks. Let me amend my plexiglass statement to Lexan, or a thicker sorrosion resistant steel so that Cecil could bolt it over the existing hole and make a smaller hole for the 2" pipe. Would a thinner gauge steel (that was the same approximate thickness as the tank) seal, or would it be too flexible to get a good seal?

Cecil, while you have a little time to burn, try sticking a bead of sealer on the black 180 gallon tank and see if it sticks. I'm concerned that you will have a hard time finding a sealer for it.
