Frag tank on the cheap

[Madreefer]

Tee in to your plumbing like this



Pumps in to your tank



Than just get a cheap external overflow to go back in to your sump



Or you can drill a tank like this and just have it drain back in to your sump. But put a screen so nothing can plug it up. I no longer have this tank online. It's just keeping some liverock alive for me.



As you can see it's a cheap easy way to plumb as I just used some odds and ends I had around
