Just a little video so you can see the fish, http://www.youtube.com/watch?v=XjLh9Jg07qQ. Having a problem with the small bell syphon I have added in the new flood & drain system. It keeps not working. Seems you have to have just the right amount of water coming into the growing bed? To little & the syphon wont kick in! To much & it wont stop! I’m thinking that the delivery tubes to the NFT will have to be changed as they are rather small & could be blocked up quite easily! As for the fish they are starting to grow recognisably into Tilapia with the head almost dropping down to the front of their bodies.
Sorry I had to correct a couple of points in the video, so here it is re-uploaded
Wow what a fiddly job this set up turned out to be. The new Aquaponic set up using NFT & Flood & Drain in Chippenham in the UK. If you want to come & see it at Bill & Bens HydroWorld you will be most welcome. Check out the link to see a video!
A good week for the project, as the fish are settled in nicely with no fatalities! They are buzzing around in the tank at a temp of 24 degrees Celcius & a steady 6.9 PH. I have arranged a bigger tent 2.4 x 1.2m to house them & extra grow beds will be created using NFT & more flood & drain. I will update you later with photos when this has been done. Contact me if you wanna come see the set up. 0790 8080803.
Massive changes have been occurring at the fish project. The College Project Site where we began our adventure is now up for redevelopment and the fish project had to find a new home and pronto. Unfortunately our numero uno choice fell through at the last minute and we haven’t had time to move the entire project to a new site. But its not all sob stories – the project is continuing as a demo unit for the next few months at Bill and Ben’s Hydroponic Garden Centre. The unit is going to be highly controlled and monitored for the next few months to generate data on optimum growth conditions – something we weren’t able to do in the polytunnel – VERY EXCITING STUFF.
The Demo set-up is rather different – where we were out under the friendly skin of our jumbo polytunnel, we now have one big IBC in a grow tent under synthetic lighting. We transported the fish across to the site on Saturday and planted up the flood and drain bed on Sunday. The next step will be to add NFT systems either side of the tent to ensure adequate ammonium take-up as we have 61 beautiful silver and red tilapia growing in the system!
We want as many people as possible to check out the system while its on its demo – get on down – particularly if you are interested in trying aquaponics yourself. We plan also on running some free workshops on IBC system construction and flood & drain siphon making. If you want to be kept abrest of any workshops, please contact email@example.com for more info.
