Having read up on the subject I'm about to have a go at making my own clear perspex inlet / outlet pipes.
The spray bar that came with my Rena XP2 filter has holes that are about 3mm dia. But I think I've seen some mention of making holes with a heated needle, which would be much smaller. Are there factors that determine a good size for the holes and distance apart?
And I'm planning on making holes (probably the same way as for the spray bar) for the inlet filter. What sort of number / size of holes will I need to make?
