Single Drain Line: Risky Business?


Active Member
How many of you run a single drain line? Has it ever clogged on you?
I want to run a single 1.5" external durso on my tank with an intake screener that extends to the bottom of the overflow box. I will be putting about 200gph MAX through the pipe.
Good plan? Thoughts? Opinions? Alternatives?

I run a single Durso on my 125 gal reef. Never had a problem with clogging. Get around 400gph through it.
You should be fine.

I run a single on my 72 bowfront. I had it clog once due to a sea cucumber finding its way down there. No problem. My overflow filled up and then the pump ran out of water in my sump. The tank never overflowed.
