Hey guys,

First up, please don't scorn the "freshy", but these tanks are freshwater:fun5: . I was not getting much input on other forums, so considering how much saltys are into plumbing, I thought you guys could help me out.

Pretty soon I am setting up (4) 55g tanks. I am using those double 55 gallon metal stands that hold a 55 on top and a 55 on bottom. The stands will each be on a separate wall, but butted up to each other in the corner.

Can anybody suggest a few ideas of draining the tanks all at once? I drain into a spare bathroom.

I'm thinking something like this, with ball valves installed so that I can drain two tanks at a time. Without the ball valve, the top tanks would drain faster and end up breaking the siphon. I would prefer a setup that could drain all 4 tanks at once, but not sure how I could do that.

a second question, could the below setup be used to fill the tanks as well, or would they fill at different rates?

Feel free to stray away from my original design. The end goal is a fast water change setup that includes draining, and then filling as many as the four tanks as possible simultaneously.
