Maurice! Fines filtration

[kntry]

Thanks for all the information. I'm going to see if I can incorporate this into my filters.

question....or two.
how many inches of down pipe are slotted to get that amount of flow?
and
the top of the pipe is just above the water level as an overflow, right?
thank you


ok, done it.
just slotted the heck out of the pipe and put the top of the pipe below the top edge of the barrel...
runs great and k1 started to collect stuf quickly.
need more k1...on the hunt
