I've never done all the mods, but I did have a seaclone. Rather than go thru the ordeal of trying to modify the skimmer, I just tossed it [keeping the maxi that came with it]. I hear there is a new Seaclone now that is a better skimmer.
as Beth said, there is a new model that works well. SeaClone has made the modifications and all the new ones should be updated.
You can tell if you have a new madel if the center rise tube is about 3-4 inches long. I have never had a problem with mine!
I did all the mods! Mine works fine in my 65gal. I know people are gonna convince you on buying a cpr or a red sea....but all I can say is that for the money you can't go wrong....
