Hi
I have been running my system now for two years. Starting off with a home made basic flood and drain as promoted on Murray's Video. I added floating raft grow beds after seeing Murray's early photos of his now promoted flomedia Grow beds, I also added additional filtration so that water pumped out of the fish tank would filtered prior to the floating raft grow beds.
Later I added a home made RAS where the water is pumped out of a sump into a bio filter where it flows into a fish tank. The fish tank which has a cente drain pipe which lifts solids into a set of swirl filters and then back into the sump. The RAS idea was based on the ideas suggested by Gary and Earthan Group, while the Swirl filter ideas were posted by Daveoponic.
I think anybody thinking of going commercial should do what I did and that is suck it and see6 (That is build and run a small system first.) So far I have seen nothing in aquaponics that would make make me want to go commercial. At the same time I have found a great interesting hobby which has produced fish and lots of vegetables at home and what can be better than that.
I thank all the forums for the information they freely make available to all.
Cheers
Joey
