Lol thanks guys.
Tonight I went and picked up two 55g barrels for ro/di storage. I couldn't justify dropping $400+ on a larger vertical cylinder and figured 100 gallons was enough to handle my water changes and topoff. These barrels were used to store crushed tomatoes and apparently the mix itself was in giant bags within the barrels. Essentially these barrels are brand new =)
$45 ea. I'm going to pickup a third to use as a mixing tank after seeing them rather than buying a 55g glass tank.

They are the blue open head barrels. I am not planning to drill these either. I want to minimize the chance for leaks down there. One barrel will simply have my osmolator in it. One will be ro/di storage which will feed into the third when it's time to mix. The feed barrel will be elevated and I am going to have hard pvc plumbed over the top with a full siphon and valve. So long as I leave a bit in the barrel it will maintain siphon and save me buying more pumps.
This will mean making some of the area under the stairs part of the fishroom rather than just having pipes from the barrels come thru the planned fishroom wall. I'll have to think more on this because the wall is load-bearing and it will mean tossing a header in there. The current 2x4s are all warped and sad looking so I imagine the effort will actually strengthen the wall!
