If you want to change the output height on your skimmer is it OK to add a couple of 90 degree PVCs to get it higher or do you actually have to raise the skimmer itself out of the water? This question is related to a Lifereef skimmer if that matters.
Skimmer output height change?

What do you mean by "output height"?
Literally anything you do to the output (where the water actually exits the skimmer and goes back into the sump), unless it is already out of the water, will cause a difference in your skimming. Likewise, raising the skimmer in the water will also have an impact causing a more dry skim.

I think I know what he's trying to ask Jeff. If your putting a 90 degree elbow to redirect the water flow, it may affect you skimmer depending on which direct you point it at. If the output if you skimmer is underneth your water line and you want an elbow to bring it above waterline then yes I think it will affect your skimmer. If it's already above your waterline and you just want to direct it to a different angle. Then no it won't because I did the same thing with my skimmer to reduce or eliminate splashing. Your skimmer will be affected no matter what you do. But depending on what you do. It may have little affects or a lot. Hope that made since in a way
I'm not familiar with that skimmer, but in almost every situation, raising the "outflow" height of the skimmer will create backpressure within the skimmer.. some models handle this better than others..
you'll probably have to raise the skimmer as well..

Sorry, I realized that was unclear as I was typing it...
Yes, the output is currently under the water line more than I want it to be, but I have it under the tank so I have limited available room to raise it. I was thinking of simply raising the outlet (via 2 90s). I gather though from the responses that the increased back pressure in the skimmer would not be ideal, so I would be better off just raising it further out of the water to ensure skimmer performance. Sound about right?

What I would likely need to do is attach 1 90 to take the flow up and then another to take the flow back out away from the skimmer.
For that skimmer, I think your best shot is to rise your skimmer altogether.
