Hey everyone, I'm building a sump and have a mag 9.5 on order and was wondering whether I should use PVC or flexible tubing based on noise level and functionality? Where is a good place to buy it? Also, does anyone have any recommendations on where to get glass panes to build baffles...

My drain pipes are flexible tubing and I cant get them to stay pointed down into the right side of my sump. I have them supported with zip ties and buttons right now but I am not trusting that at all... How can I make them stay pointed in the right direction? Also I dont want them to grow algae...
