The water in my wicking beds smells bad.  I placed sand in the bottom to the height of the overflow.  Therefore the top soil is in contact with the water reservoir.  Should I have placed more sand in the bottom?

What small water creature would be good to eat all the poopie slime from the bottom of my water raft bed?

My tilapia eat ALL algae that grows in my systems. If algae grows in the FT they eat it down to a green sheen on the surface. They will graze on it as it grows. If I am busy/lazy for a while and algae grows in the troughs then I scoop it out and put into the FT and the tilapia eat it. I have never considered introducing another species other than tilapia and koi to the system because they do all I need.

Hi Chris, what exactly is the tower made out of. It looks like a downspout, but much larger.

Dude, you had to mention fishing didn't you. Oh how I envy your situation. I haven't dipped my pole in over six years... so catch one for me buddy! Grill it up and take some pics,; then at least I can dream and drool.

Hi again. Thank you so much for your cooperation. I too would like nothing more than to develop this market. 


I would be glad to help in any way I can.  I'm not being negative or standoffish but my plate is a bit overflowing as is. In fact, this site has become a form of relaxation/ respite from reality. But if you have the OEM (original equipment manufacture), we might very well be able to do smaller shipments and make/save some coin on the side.

Thanks for adding me as your friend. Is it ok for me to use some of your pics as a good example of small home system? I love the pics with your daughter eating that big red strawberry. Too cute.

Chris, I found a post from you under a discussion regarding aquaponics business plan.  It was of specific interest to me as I am trying to start an aquaponics business in North Carolina.  Is it possible to get a copy of you latest business plan?
