this thing is great, i wanna build one for more of toping off the tank not filtering reasons. so i just have a few questions.
1. I know the pipe on the outside of the tank with the open top is so a second siphon doesnt start, my question is does it have to be so long?
2. How thick of PVC do i need to use for a 90gph pump, so that the tank doesnt overflow? 1/4in, 1/2in, 3/4in, 1in? i dont want it to be to thick i only have a 20gal.
3. Do the pipes need to be glued together, and if so what kind of glue?
4. Lask question, how long do the pipes inside the tank have to be? or does it not matter?
thanks for all the help and for this great DIY.
