OK so i dont post much on here cause i really dont know much lol but i thought for all those that have this skimmer might enjoy this. So ever since i purchased my corallife super skimmer 220, i wasnt never really pleased with the skim at all, some times it would over flow and go crazy and most times it barely skimmed. so on a routine cleaning of my skimmer i noticed the shaft in the needle wheel was broken in 3 places, i called corallife and spoke with a rep, and asked him if there were any mods i can do to get a better skim since i wasnt really impressed, besides the more popular mods that we all now, he told me i can actually increase the pump up to 950gph, so i went out and got me a mag 9.5 needlewheel pump hooked it up and within minutes i noticed such and EXTREME DIFFERENCE in color of skim, foam production, i was completely amazed! i now have a new hope for this skimmer, it finally is a SUPER SKIMMER with the upgrade to the pump.
