Bloody shiping people! My stuff did not come on Friday. Usually it only takes a couple days go get here from Big Al's (email conformation said it shipped tuesday morning) Oh well. maybe monday.
In the mean time, I will have the opportunity to work on my intake and outputs. Does anyone have any suggestions about th econfiguration of the intake and output? I was planning on making an spraybar for the output, drilling holes alon the length of a piece of 1/2" pipe and capping the end. It will run from front to back on one side of the tank, the intake should be on the other side? How many holes and what size? Do they need to be bigger toward at one end to allow for more uniform "spray". I was also planning on having the back holes oriented so they flow almost straight across the back but angling down a bit so that the point almost down in the front, to help keep the foreground cleaner.
For the intake I was going to do basically the same thing but vertically. I can machine in slots rather than holes near the bottom to act as a strainer. Would having some holes near the top help to achieve more even water flow. A hoel near the top might also be insurance for leakes. If the pump of filter sprang a leak, hte suction would break when the water surface reached the hole, about 1" below the normal water's surface. Any ideas about the size of the slots or holes to allow good water flow and suction without robbing it of "power" Remember that the pump is rated for about 275gph where it will be located but will definately be lower than that with all th eresistance from the filter, elbows over the tank rim, CO2 reactor, and there will be a ball valve after the ump for flow control.
Any ideas? Maybe IUknown can chime in about his lilly pipe design
