Hey can someone give me some advice? I have one python and will soon have two 55 gallon tanks. I currently have fish in QT with salt and Prazi and have been using buckets and a hand held siphon (old school) because I do not want my current tank to get a fluke (or any other nasty) outbreak. Will I eventually (or now) use one python for both tanks? I am afraid of any cross contamination. Is there a way to disinfect it so I can use it on both tanks? Can flukes stick to plastic? I do a lot of water changes (sometimes 3 times a week) and do not want to bleach it between tanks. Or am I going to have to break down and buy another? Advise is appreciated!
