Yeah I believe you guys are right and the bottles will be impossible to seal correctly. Also right about the pressure. It said on the water pump box it pumps up to 2 feet up. (It's one made for fountains) It would probably have enough power to get it up there but I don't think it would properly distribute out the spray bar.
Sooo, I will be redesigning and looking for things to make it out of. I thought about using tupperware containers (the ones with a rubber "o" ring and they snap shut) They are easy to find and cost effective and won't flex that much so I could probably seal a lot more effectively.
lol, so by the time I end up building all of this I could probably get a Zoo Med 501 canister cheaper. I just am not sure if it would be adequate for my 10 gallon. Says "Up to 30 gal" but I've also read that that means a 30 gallon tank if it were half full (for turtles) so that equals 15 gallons. Although I do only have shrimp so it's not like they put off as much waste as fish do.
Input? DIY or Zoo med 501? lol I'm all about DIY with EVERYTHING but sometimes it's just easier and less of a headache than building something. And since it's only a 10 gallon I don't need crazy filtration. Hmm
