Paul, did you give up on your DIY skimmer? Mine is still in sevice and making my evening cup of coffee daily eewwwwwww. It has stayed consistant at 3/4 to 1 cup every day.
I would agree though, don't waste good money on a visi-jet or tornado toy (seaclone). Just do good steady water changes until you can get a real skimmer. Your tank won't blow up without a skimmer on it. Some people don't even use them at all, they just keep up with thier water changes religiously.
