Good morning, everyone. As some of you know, I recently visited the island of St. Croix and Mr. Don Bailey was kind enough allow me to get my hands dirty one morning! Needless to say, I'm ready to start digging. The photo below shows a quick & dirty drawing of what I plan to do. I think the text will be a bit blurry, so here's a quick description:

Fish tank (Size TBD) flows to
Filter (Size TBD) Flows to
Constant flood gravel bed 20' x 4' x 16" flows to
Flood & Drain gravel bed 20' x 4' x 16" flows to
DWC #1 20' x 4' x 16" flows to
DWC #2 20' x 4' x 16" flows to
Sump: Size TBD, whateve size can hold the volume of the flood & drain bed and then some.

I'm planning on building the beds like Colum did his. Galvanized pipe, wood, liner. Although I haven't discarded the idea of doing it like UVI, which is cement blocks & liner. Bosswife likes galvanized, as we can move it if we want to. (Or get rid of it easier).

Any thoughts?
Thanks!

I wouldnt flow from one DWC into the other,have separate flow for both.
If it was me i wouldnt bother with the media beds,just have one or more DWCs,filtration being RFF and then onto net filter/filters,the DWC suppling the Bio filtration requirements.

Thanks Dasboot. Still debating on whether to plumb in series or parallel. Also, I'm liking the idea of eliminating the gravel bed and go with 4 DWC's (But we'll see!). Here's my latest sketch:

I would still use four inlets four outlets,if you have the four inlets at one end with a T piece at the inlet providing you have the flow and all inlets are at the same height you will have equal flow through each bed,you need a common manifold to supply all four,then at the inlet height a T piece with the T being the inlet into the bed,gravity will then sort out the levels for you and as i said with sufficient flow all should be equal,hope that makes sense.... :think:

Good morning, everyone! After giving this project more thought, I'm now thinking about going with DWC's. The photos best describe the project. Ideas / constructive criticism?

Thanks always, Felix

Looking north. palm & gardenia are going to be pulled out next week, compost pile going to mom's house.

Looking South. Great wall of China, bananas, lemon, cucumbers in dirt.

In case you're wondering who lives in the cage. Just showed up one morning, later in the day he was still around, so I kept him. Loves earthworms for breakfast. Eats boiled eggs, plants, cockroaches, centipedes, and just about anything I can dig out of the compost pile. Bee killer...

Looking east: Ugly Roofs, Las Cabezas de San Juan Lighthouse in distance.

I'd be tempted to keep the compost pile for fish food :think: . Are you going to put this on solar?

Hi Scotty. No solar (at least not for now). I'm running electricity from the other AP system on the side of the house. Electricity (and water) will run along the perimeter of the yard. One waterproof box on the corner to the right of the palm tree, one in the corner of the Great Wall. By the way, we named the wall after our neighbor (China) who built it!

Scotty, told the wife about your suggestion, and we're considering solar. The PV panels could provide shade for the fish, and Im certain I could hide the batteries & system back there. Now, would I use a 12V DC pump or a 120V AC with an inverter?

I'm hoping you'll figure all that out for me but I think in the past others have found the 12V DC pumps didn't hold up as well. Might be worth asking those who know about these things, opinions change and new models come out. I've been wondering about some of those little DC pumps, they can really push water and are cheap compared to the AC models (A person could afford several backups but I don't know if they are worth it :dontknow: ). I don't know if the cheap ones like the Tsunami bait well style pumps would be high enough capacity for your system.

Hi everyone. Well, it's been a while. Spent Christmas & New Years in Washinton, to come right back for shoulder surgery. Needless to say I won't be digging for a long while. For now I'll keep eating, gaining weight & drooling over Dasboot's system! I suppose I have time to plan my tank & filtration well. I was planning on using a 600 gallon tank as a fish tank. Do you think this will be enough to "power" this system? Any suggestions on filtration (sizes/volume)?

On another note, before we left we dug out the palm and gardenia as planned, and sent electricity & water. Will post pics as soon as possible.

Thanks always,
Felix

I think you need to know the volume of the DWC to get a better handle on whether the fish tank is sized right since each square meter requires a certain amount of nutrients. I'd plan in a mineralization tank since it will reduce the fish load needed to run the system. You also want to turn over the fish tank once per hour and the DWC once every 1 to 4 hours from what I've read. I'd keep looking at Dasboot's system and figure out the order of the components and flow through the filters.

Hope you're feeling better soon :wave:

Thanks Scotty. Definitely going to use an MT like Dasboot's. I'll start going my calculations. Troughs will be 4' x24'. Haven't decided on the depth.

Thanks again!
