Louise replied to Louise's discussion What's good on a raft?"I'm letting the media grow bed filter the water from the fish tank, then from the sump tank it goes to the raft tank before returning to the fish tank.

R.K. Castillo replied to Louise's discussion What's good on a raft?"Are you doing any type of filtration before the fish tank water goes to the raft? What's going to act as the bio filter to grow the bacteria?
As for plants, it seems like lettuce & herbs do great in a Raft System. "
John Cubit replied to Louise's discussion What's good on a raft?"Sure if you concider my lettuce is only 6" tall and the chard is 13". Other plants I have placed in the DWC that did well were, habanero seeds, pole beans, snap peas, leaf lettuce and broccoli. All of these have been moved to…"
sticky replied to Louise's discussion What's good on a raft?"Yea, but isn't that basically another lettuce. Maybe not in the same family, but very similar in plant type. From what i have observed is that certain plants need to get air to the roots. So a DWC set up wouldn't facilitate that, i guess…"

Bob Campbell replied to Samson J. Loo's discussion Pumps, Piping, Fill and Drain Rates in the group Arizona Aquaponics"Larger is better, but larger costs more to operate. The initial price of your pump pales in comparison to the cost of operation so look for efficiency.
My experience shows that the water flow is not critical. I'm not saying a…"
Jeff Navarro commented on Jeff Givan's group Ohio Aquaponics"I'm building a 6x11 grow room in my garage made with 1/2 rigid insulation with a heat barrier on the inside. My garage is already insulated but no heat so I hope that by building a smaller room inside will help control my temperature.I plan on…"
John Cubit replied to Jim Enterline's discussion Leaf Curl Problem"Just my 2 cents. I had the same problem with a dirt grow bed and with my ap system, specifically with Tomatoes and Hot Peppers (all varieties I grow) What I have found was that the plants are suffering a calcium deficiency. Adding…"
Brian Hillestad posted a discussionWater change
I have a +/- 600 gallon tank with tilapia that has gone quite green. I have tried covering it, feeding the fish less, etc. Nothing is clearing it up. I think I need to do a drastic water change to clear it up, but want to know how far I can push the change. I have about 35 tilapia in the tank. Any advice would be appreciated.See More
Robert Rowe commented on David Schwinghamer's group Arizona Aquaponics"@Jim - Normally the sump pump output is divided between FT1 & FT2 with the volume proportionate to the FT size. During the 15 minutes the Grow Bed pump in FT2 is on, the sump is receiving more than it's sending and at the shut off…"
David Ries replied to David Ries's discussion my nitrite levels just jumped sky high"kieth,
I have no idea why my plants are doing so well with only a couple hours of direct sun an evening. They all started out as little plants in the quad holders, about 3" x 3" and now most are 4x their original size if not bigger.…"

Pumps, Piping, Fill and Drain Rates
I almost felt like adding "and me. This sort of thing is my bag baby" to the title as it reminded me of a quote from Austin Powers.I have read that it is advisable to have a pump that can circulate twice the amount of what the FT holds. So if I have a 275 gallon tank then I should get a 550 GPH pump. Is that a minimum requirement or can I opt for a higher volume pump like 600 to 800 GPH? With that said what fill and drain rate should I aim for? I know I can use a ball valve to control the…See More
Louise replied to Louise's discussion What's good on a raft?"Funny! But I'm surprised we're not getting any real answers to this.
I had some low styrofoam boxes with holes in the bottom, for drainage. I made this little experiment, but it's still too early to know if it works: I put a thin…"
