Although not new to aquaria, I am very much a beginner to salt water. Recently, I converted my 55g Cichlid tank to salt, the results of which have been fascinating, time and thought consuming.

This past weekend, I converted a disorganised pile of in sump pumps to an in-line system with pvc. In turn, I have a bit too much noise and bubbles coming from the return.

The water level in the sump is fine, its over the level of the return intake. The bubble problem comes from the protein skimmer (Aqua C EV120) return being dumped into the same chamber as both of the intakes.

Without moving the protein skimmer, I want to eliminate or seriously decrease the bubbles. I think this would decrease the noise of pump cavitation and at the same time make my tank look much more appealing.

Suggestions?
