Hi there, I bought my ER back in April, but just got to start using it this past weekend. It's a CS 6-2 on a brand new set up 120 gal tank with 30 gal in the sump. I know it's probably a little undersized for my system, but it was the only footprint that would fit in my sump intake area. Anyway, a couple of questions:
Again, the water is new and the tank was set up with rock from two well established systems, so no die off from the rock. Only have 2 very small fish in the tank right now. The ER is foaming like crazy, but nothing is getting close to getting up to the collection cup. Is it just a matter of the water still being too clean right now, or do I need to adjust somthing? The bubbles are coming to the lower part of the neck of the skimmer.
Secondly, the Sedra 3500 pump is, from time to time, making funny "grinding/whirring" sounds that are quite audible from some distance away. It will do it for awhile, then stop doing it, then start it again. Any ideas on this? The skimmer and pump are sitting on a little table I made using eggcrate to get it to the recommended water level in the sump.
Thanks for any help and sorry if any of this has been asked before, I'm at work and didn't have time to read all 30-some pages of this thread during my lunch break.
