So, I think to make life a bit easier, I will use the end holes for the overflow and return. I have a few more questions...Bare with me, these questions are probably stupid and simple but I have never done this before...
1. These are 2" bulkheads, what size PVC should I be plumbing the drain line with and will 2" bulkheads not be a bit much flow draining from a 115G tank? What about PVC size for building the standpipes? (I have never built them before). I have a whole bunch of 2" and 1.5" PVC that I would like to try to use if possible.
2. What is a better option than a durso standpipe? I have used them before and they were still a bit loud...maybe built wrong though?
3. I know acrylic does not bond to glass well at all. What do most of you do to solve this problem if you build an acrylic overflow? I guess its not really being used under pressure and the "suction" from the water flowing over it, may help keep it in place? Sorry if that sounds like a stupid question
4. What about painting the acrylic overflow? I would rather use the acrylic I have than buy black stuff. Are there any paints that are safe INSIDE the tank?
5. Same question are earlier, what about plumbing rubbermaid type containers together? How well does this work? I would need to connect them...
6. Whats the best spot in Vancouver to buy plumbing supplies? I have had a hard time finding any 2" bulkheads or anything for 2" PVC. I have a bunch of 2" PVC and would like to use it but can't find elbows, unions, valves, ect. in that size...only abs stuff.
I think I will draw a few of the plans up soon and that may help you guys help me
Thanks for your help though!
