Reverse Flow UG

  • We are currently upgrading MFK. thanks! -neo
Sunday is fin high WC day, Ranger. Let's pick up the pace as you've got a handful of us in the background wondering if we should turn back the clock and try a backfed UG filter again.

In my case I have Giraffe's so I might be able to sidestep the work but yeah, inquiring minds need to know.

I've got the stand built and level now it's tank time! I'll be sure to take some pictures. The reverse flow worked so well on my 300 gallon many moons ago that I can't pass up the opportunity to do it again with a lot finer filter media. When I had it set up my gravel was always clean. Believe me a bunch of large well fed Tinfoil Barbs will have you cleaning the gravel to often with a standard flow UG. I'm going to be using 2-3mm gravel/substrate and I have already tested the flow in a plastic rectangular container with this small substrate and the upwards flow was really good. A 4'x8' gravel bed 2-1/2" deep should work really well.
