Was checkin out the SLO/standpipe design here:
http://www.rbmaqua.com.au/documents/RBM ... y-_000.pdf

Now i've got a couple of questions,
1. if this SLO design is right, doesn't it drain through the bottom of the tank as well, so it it got a leak in it, wouldn't all the water run out?
2. does the SLO pick up solid fish waste well enough?

Thanks
Davi!
