Is this bad?

[freshfish]

I picked up a pump for my ETS skimmer and of coarse its to big so I put a gate valve on the output side to tone it down a bit is this ok? The pump is a pan world 50 xx or something like that 1100 gallons an hour. I had a mag 12 on the skimmer and I figured that would be close to the same amount of flow with this pump. OOPS no comparison. Well instead of getting a return pump and leaving it alone along came this nice pump for a good price so I had to upgrade of coarse:deadhorse: does it ever end? Probably not.

I would think that a gate valve would be any different than some head pressure. As long as you are not cutting the flow drastically, it shouldn't hurt.

What skimmer? I have a BL 55 pressure rated, 1100 gph on my ETSS 900

I think it is a 500?

An Evolution 500?? That's too much pump, major throttle back, they are recommending 500 gph through it......

I know over kill.

I mean it could work but you'd need to throttle both the pump and potentially the air intake. Downdrafts take in A LOT of air with a properly sized pump, with an oversized pump even more so :)

In this situation overkill is no good. Pan it back alot or use somethign smaller

I had to tune it back. I took the gate valve off the output of the skimmer and had to put the gate valve on the output off the pump otherwise it just filled up the skimmer.

:icon_rock: overkill huh chad

there are a couple of possibilities with DD.....both essentially do the same thing. Either put a gate valve on the pump, which throttles the water and air inputs to the skimmer, or put a gate valve on the air intake. I prefer the latter. You'll still have a monster skimmer....
