Thanks everyone, as soon as Joe and I finish this house and one other project I plan on setting up my 220 gallon frag tank that will be plumbed into the system and contain a dsb. I have just been so busy with the houses we are working on and a beuatiful 6 month old little girl. I must say that she has been more fun to play with than my tank. She changes everyday and my tank does not, so maybe I am just a touch ADD. I did clean my skimmer and all but one of my Tunzes tonight. I also just ordered another Tunze 6200. This will be my first 6205 so I am curious to see the differences. I will be running 2 tunze 6200s, 1 x 6205, and 1 x 6100.
