I have an ATO compartment in my sump that holds almost 7 gallons, but I've realized I want a larger one with another ATK kit, so that my ATO gets topped off by a larger ATO. Kinda dumb, but this is how things get.Thanks! I am pretty happy with how it turned out. Decided last minute to add the T for a manifold down the road to run a BRS Carbon/GFO Reactor.
Just placed an order for my ATO container. It is the last major piece I needed for this build.
