Using one pump for 2 tanks

Boujii · May 13, 2014

Hello my new friends,
I've been browsing around the last couple days here and reading some threads regarding joining 2 tanks together.
Most responses were geared towards U-siphon and bridges.
Let me explain what I have and would like to set up and see if the guru's have any suggestions.

I have a 150g and a 90g I would like to setup in a "L" shape and have them use one pump.
With the exception of ball valves I forgot to draw in, would this method work?
I heard that water levels itself out. So I am anticipating; as long as the flow is not too fast; this might work.
I am looking for and suggestions. I would rather not use a bridge or U-siphon and prefer the hard line method.

Appreciate any comments

With the addition of the ball valves to adjust the water flow into each tank, I think it would work just fine. The distance each tank is from the pump, and the elbows used is going to differentiate between who gets more water.

I have one pump running 4 tanks

Good deal

The last thing I want to deal with at any time is flooding so I figured this is probably the best method. So long as no blockage from the 2 inch line coming from one tank to another.
A slight issue is I will have a strainer on each end of the 2 inch line to keep the fish separate. This might decrease the flow a bit, but I hope not enough.
And as mentioned, the ball valves can be used just in case

I have one pump feeding 4 tanks as well. Just make sure you have enough "pump" also ball valves are a must.

You can take a look at my build thread - i have a video of my sump room - I have each tank has its own drain into the sump and my pump has a line to each tank controlled by a ball valve.

We have a frag tank and nano plumbed in with our 175. Just make sure you do a test run to ensure you have enough room in your sump for the water from both tanks if the power goes out.
