Got my own home system working much better. Today I tested the water. Fantastic results. Ph of 7.5 and NO2 and NO3 almost negligible.We had been having a lot of heavy loads from the tank clogging the filters and the pump. So much so that is was beginning to go terribly wrong. Even the large flood and drain bed was accumulating algae. First off was to redo the syphons. We made them a little shorter to ensure the water never came up above top of gravel. I know easy enough but when we did the beds we ran out of energy to put in more gravel.. So being lazy finally came home to roost as it were but that's now sorted. Second big job was to remove some of the small fish we had. I thought we have added a lot but when you buy a kilo of cat fish they take up a lot of space. I reckon I removed about 150 small fish. We sorted them out. Kept 7 big Tilapia and the rest went into our main farm pond. Hopefully to grow and finally arrive on on plates in due course...
Next up for December was meeting with James Racoky of UVI fame who is the world renowned expert on Aquaponics. He has retired and lives in Pattaya. Owen and I met him for a quick coffee. 2 and a half hours later we left. Very interesting and exciting stuff. Go me more pumped up about the whole thing.
The four pictures above are of the 1000 litre system. We are going to have a very similar construction to this one.
Following on from such a meeting was then catching up with Robert 'Bob" White at Chat Takarn. Bob has been instrumental in establishing the Association of to see a small system he had installed in a local Wat, and see his other new UVI type system in its construction stage. Really got me all fired up to get started. The small system is a 1000 liter fish tank feeding about 10 meters of flow beds. The big system is 4 fish tanks of 7000 litres each. Big and very interesting. I've added a few random photos of the systems and as you've guessed I've got a load more to help me understand what is going on. Ready for me to start on mine...
To keep me going through January I have bought a small system off Bob. He is due to deliver in first week of January. That's the 1000 litre system. It should produce all the greens to fed the whole family and more... We should have it up and running with in days of Bob making his deliveries. Getting excited about this. Bit like waiting on a Christmas present.
Then our big project. We are going to build one similar to the UVI system on our land. I mentioned before we met with James Racoky of UVI. He was really helpful to support us in this idea. Already got the spot in mind. We have flat raised land, power and water. Also already have a lot of ancillary stuff. Office, store room, pumps, plastic pipes and lights etc. Just need the fish tanks which we'll make out of concrete and the various filter beds and grow beds.So now need to finalise costing and make sure it pays of itself. Then February/March we start the big system.
The last photo is form our tank. Modest but a success.
Happy New year for 2013.
