I received the AquaC Urchin Pro today. I half filled the sump and tested the skimmer to see how it discharges. The skimmer came with a MagDrive 3 (350 GPH
) which I ordered. With the skimmer running, water flows gently out of the unit and runs down the side of itself. No bubbles are discharged and there are only a few large bubbles that are caused by the discharged water entering the sump water. If the sump was filled I don't think there would be any bubbles at all.
At this point it seems that the sump/fuge should work as originally planned even if the skimmer may have been better placed on the inlet side. Either way - I'm always learning and always open to your suggestions.
Thanks for everyone's input.
