Post up some pics of your fish room with multiple tanks. Let's see what you got and how you have it set up.
Brilliant! Very niceFrom left to right 360, 450, 120, 180.
Then some pics of the plumbing. Having multiple tanks in one room make plumbing easy. I have incoming water to 4 T fittings that go to each tank for the trickle system.
The drain goes around the back of all the tanks and the sumps are plumbed to that drain. I extended the drain up into the stand of the 450 so I could put the python gravel vac in there so no more buckets. I also can hook up my canister filters and drain them before changing out the cartridge, again no buckets
The drain leaves my house in a 1.5" line and is buried until it gets to the bushes, then I ran an old garden hose to each bush tree. Every couple days I open another plug to move the water from bush to bush.
