Reading about the Durson Stand pipe, he claims to use schedule 26 because it's a thinner wall. Does anyone know where to find schedule 26 fittings??? Thx in advance...
no wall thickness doesnt make a difference for fittings as 1.5" sch 40 and 1.5"sdr 26 both are the same O.D. of 1.900I would assume you want 1.5" fittings for the Durso type stand pipe. It has been my experiance that the wall thickness of the fittings does not make a noticable difference. I am using regular old sch 40 on my tanks that have the durso type stand pipes and they work just as well as the one with the thinner wall fittings.
I have also found that this type set up works better if you use a "bell" type reducer fitting for the transition from 1.5" down to 1" as is typically done. The bell type have a smooth taper from 1.5" to 1" for a smoother & quieter flow of water. THis type of fitting is not found at harware stores normally. If your local aquarium shop doesn't carry these you can order them from champion lighting. (www.championlighting.com)
