I'm back .Since I have been, to say the least sick for a bit and not posting as I have not gotten much done the last few weeks . I am up to about 1/2 speed and trying to get back on things . I am getting the beds built and just was thinking (b4 I drill holes ) if it really makes any difference where the siphons get mounted . I have seen them mounted at the side ,in the middle and on the ends . Being the bed is flooded I'm not sure this makes any difference at all but figure I would toss it out and see ! So any opinions on where the best place to mount them or pretty much just on the bottom

This also raises another question . On the fill side of everything I have seen single dumps at one end of the bed , T'ed with an outlet on each side and full ring with holes around the full perimeter . I really see no difference as long as the bed fills although the full ring looks fancy but I don't seem to see the point of wasting more pipe if there is no need .
Just for the record the beds are 3'x6'.
Have A Kind Day
