How to plumb together multiple tanks

[Wolf89]

How do I plumb 3 or 4 tanks together? I have a 90G dt, a 40G breeder fuge, 15G sump and a 20G observation/safe space for maybe fish that are getting bullied or fry and anything that needs to be alone.

I plumbed a 32 gallon biocube and a 55 gallon tank to one 20 gallon sump, I just have a separate return pump for each tank. I thought about adding a 3rd tank until I simulated a power outage and realized that if I add another tank the sump would overflow but did fine with two

If your return pump has the output you could build a manifold with valves to each tank.

I have it set up with using only one strong return pump with ball values to corntorol the flow into each and works great.

Sump feels too small imho. Do u have room for something bigger? Again imho you could never have a sump too large lol . u def need to take in to account drain down in a power outage / shut down.

I agree...large sump, strong return pump and a manifold...
