One Aqua C Remora skimmer for the 20g and 2 koralia 4s for the reef. I have found other uses for the maxijets so I figure it is a good deal all aroundl The koralias are on back order but it let me place the order together so I saved on shipping at least.

Someone recommended them and their prices were just a bit less than everybody else. There is no real hurry on the pumps just the skimmer so I figured it made sense to just order. If they have good service I will try to get them to become a sponsor.
I am very excited about my new toys. Hopefully they will improve the flow and reduce the heat at the same time. Plus I really needed a skimmer for the 20g tank.
No burning I don't see any advantage to changing the current every few months. I do like to run them on a wavemaker to get intermittant flow but other than that once you get things running well I would leave them. I am trying to increase flow and reduce heat so that is why I am changing mine.
