I'm greatly enjoying seeing people like us Daytoners that have sick senses of humor. I will be going to get a siphon, but I will not use my mouth. That gives a whole new meaning to the term "potty-mouth".
I dont deny that there are less icky ways... It works for me though and its how I taught my self to make sure my fishys tanks are clean, my husband gives me a hard time occasionally but Ive pretty much got it down to were I never have to worry about tank water in my mouth. - and fwiw my putting this out there was for the sake of fish not living in there poo!
