Still considering skimmer options for 125g. mixed reef. I had decided on th DOC 9010 (with mods to convert to "collection hose" instead of supplied collection cup), or DOC 9015 (which includes larger collection cup/reaction chamber), but could not make up my mind.Then I ran across the REEFPACK 500, and wonder if this would be a better choice? I plan to keep a mixture of hard/soft corals/clams etc. Is anyone running any of these? Please advise.
