lets get this straight I have never said any of those skimmers will not skim, so if you tell me you got a cup everyday of black brick stuff, can you imagine what is not skimming in the tank, and if you were getting that much crap a day with a below average skimmer, can you imagine how dirty and how bad your husbandry in the tank is... pretty scary...
Get in to reef central forums and go to product reviews and you will see what peoples opinions are on different brand of skimmers...
If you paid 4xthe cost of the coralife for a deltec "awesome choice!!" and you are completly satisfied with the cheaper skimmer then why not buy another coralife....
I rest my case lol..!!the next time I go to jim's in kingston I will show pics of crashes and disasters I had to fix over the years in my maintenance trips...
To me use garbagge by all means it's just more money in my pocket if you know what I mean...
