I found it used on craigslist. It was used on a farm as a water holding tank. It took a while to talk him down to a decent price.
It is around 430 gallons and I got it for $250.
He had said it was 600 gallons and I was going to use it as my fish tank but it will still make a good sump tank. A round fish tank is better anyway.
Since it is tall it will be a good sump tank it keep water over the pump. But being tall I will need a pump that can handle more head to get the water to the fish tank.
So I guess it a compromise like everything.
You can see the black bottom plate in the top picture I will pit that in the ground first. it will help insulate it and protect it.
I have some Styrofoam sheets to put around the sides to help insulate it and protect.
I bought just two PVC fittings and a spicket to go on the IBC tank. I have it up on a stand and my fish tank is downhill so the water flows nicely out of the IBC to the fish tank.
