Hello to all. I am located in Silay City, province of Negros Occidental in central Philippines. At present I have a working 4 sq.m. DWC and a 2 sq.m. GB, both supported by a 2 cu.m. filtered tilapia tank. I also operate a 6000 breeder tilapia hatchery that supplies fry to the local industry. My wish is to somehow utilize the soil pond water to support large scale aquaponics. How to filter the water to prevent root rot is a problem that has stumped me . Any ideas ? Thanks.

Hi Cris. Nice to hear from you. :D

Maybe a 'swirl filter' to remove the particles ? I know people make them out of the plastic 55 gal barrels. Maybe this wouldn't be large enough for you ?
I'm sorry I don't have a 'link' handy on how to make one. Someone should come along soon to help. In the mean time , you could use the 'search' for swirl filters.

Good luck...looking forward to some pictures.

Dave

Thanks Dave. A conical swirl won't work, I think, because the problem are the light suspended solids which go with the slightest water movement. A fiber or sand filter may be a possible approach. I tried direct flow thru and the muck accumulated on the roots and caused root decay. I will try to retrieve some of the photos I took of the experiment and post them here.

I would suggest a sand filter that can be back washed as needed.

I was thinking, what plants were you growing and was this a flood & drain ssystem, or just a flooded system? Many plant need the F/D or their roots will rot.

Cris Gaston Welcome to the Forum ... Glad you could join and hopefully you will share some of your expertise on Tilapia breeding and raising.

The experiment was on lettuce on floating styro inside "hapa" nets in a big soil pond. The suspended solids (mud) in the pond water accumulate on the plant roots. Plant survival is about 50% with poor growth rate.

Hi Jack. No problem there. Will help out any way I can. I specialize in hatchery operation.
