Jeremy –
Re: "One other thing: When you use a 20 oz soda bottle as your water bottle like I typically do, sucking the water through causes it to collapse due to the pressure and then you have to briefly loosen it to make the bottle reshape. This does not occur with soft side bottles like platys."
Thanks! I got focused on the purification part for a while. Your comment just saved me tons of disappointment and aggravation in the fiddle-factor department. After reading from other threads, I had decided to go the soda bottle route. Now thinking I'll use Platy. (hope it'll fit…it's not as convenient shape as a round soda bottle..have to run to store & check one out!)
To all respondents:
Thanks so much for your knowledge and insights. Your generosity in freely sharing from your hard-earned experience is much appreciated by this noobie!
