Plumbing

[IronCityRockers]

I am building a 300 reef I bought from a friend. He had the drain plumbing 1" flex hose and the return as 3/4" flex hose. I am going back with PVC. I am wonder if the 1" is big enough to get proper turnover. I'm looking for others opinions. Thanks

I'm in the camp that prefers a low turnover through my sump (roughly 1X per hour). Do you have a preference on how much flow you'd like to be getting through the sump?

I have a 1" on my 75 gallon. I would think you would need duals or larger.

On my personal 180g that you seen, it ran two 1 1/4 in drains. One at full cyphon and one as a trickle.

I say this to say on a system that big I feel you need a emergency or a secondary drain at a minimum.
