1 Drain pipe Faster than the other?

[asonitez]

I have a Dual Overflow setup where the megaflows are on the back wall. I have 2. Both of them dump into the far right chamber of my sump.. The skimmer chamber.... THe problem is that one of the drains is SUPER FAST and the other train.. NO SO MUCH!... its pretty much not that great at all..... Is it normal for 1 drain to drain faster than the other drain? Is there anything I can do to make this a little better?

Is the tank level?
If not the low side will drain faster.
You could raise the fast one to even them out.

One drain is likely slightly lower than the other and pulling a full siphon, which would not allow the tank to fill to the point where the second drain also pulls a full siphon and thus has a lower flow. I don't see this as a big problem or are there other concerns (like noise)?

Cap the fast drain briefly, if the slow drain doesn't speed up, then it's clogged...
