Setting up two sumps on one aquarium.

[Brandonsegula]

So I have a 75 gallon with a sump and I was thinking about. Getting a frag tank and plumb it into the DT I also thought it would be nice to add another sump for the frag tank but idk how I can plumb everything together. Anyone have any ideas?

Not sure why you would want two sumps, but they either need to be equalized with a balance line or else have one overflow to the other. Otherwise eventually one is going to overflow and/or the other go dry. Even with the balance line, the two systems are not well mixed together and you could get very different water parameters. Having one overflow to the other would be the better arrangement.

It was just an idea I’ll probably just tie the frag tank to my one DT sump

IMO if you want two tanks on two sumps all connected you should either have it be cyclical or the frag and DT tank should drain into the first sump which drains into the second sump that then returns to both the drag and DT. Keep in mind if all systems are connected whatever effects one tank effects them all. Also make sure there is enough room incase of a power outage. There needs to be enough room in the lowest lying sump to take all the water.

True I’ll just keep my one sump. I just want to start dragging my own coral. I have a homewrecker, serial killer, fox flame, headbanger that I would love to frag
