Hello I am trying to figure out if clear plumbing would be a good or bad Idea I know different types of PVC, acrylic and plexiglass are composed of chemicals that vary in each product. I have a few reasons for asking 1 is because the overflow has standard white PVC and if a fish friend happens to get in to the over flow I would like to see if it was sucked down. also I want to be able to monitor flow. so what do you think? is it a good Idea if so what type is good and how would i seal the connections and where is good place to buy?
