Hi Mike, Neat trick, about putting more holes at the far end of the spray bar! First time I ever heard that idea.
Wow! That's a great pic aside from showing the micron bag. Bet it clogs up pretty fast because it's 5 microns? But, I'll bet, too, that the water is crystal clear!! Do you rinse & reuse them? If so, how many times?
Also, I want to make sure I understand everything - you don't do any vacuuming or siphoning anymore? Just use the water motion to keep everything in suspension and into the overflow - is this right?
