December Update

Well for me this has been a very exciting month.

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.


Above is Wanna reviewing the large UVI system construction. I think she is hooked as well.

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.

Changed My Filter System

The water has been getting a be dirty. The filter system did not work properly.  So I've added to half barrels, one with baffles and one with the pump.  The one with baffles also has a toilet flush in the bottom so I can drain it when needed. Not so good but best I can do with a DIY, no cost solution.  WIll monitor progress over next few days to see how water responds to this.

Progress





Yesterday I redid the plumbing changing the big sump tank into exactly that. By removing the cat fish and using it as a proper sump and additional settlement pond. So this morning after taking the dogs for a walk I had a good look at it all again.  Very pleased with the result. The sump tank is replete with clear water and the overflow filter bucket is doing a good job.  I can improve on this with some better shaped and more filter materail. Thats a job for me to see to in next few days. First find some filter material....
But this morning I could not stop myself adding a few progress photos.

Revamp of system

Been having trouble with the pump clogging up. Noticed a lot of fish waste going into the gravel beds. I realized this was due to the cat fish I was keeping in the lower tank. Nothing was filtering their muck. I've now transferred them all into the 200 litre blue tank joining the existing fish. All seem happy enough. Now I'll monitor the cleaning out of my filter bucket and see how we can add some more improvements over next coming weeks.
They system is beginning to resemble something out of a mad professors laboratory with odd pipes here and there. I've got far to many holes in the blue tank and lots of stop ends etc. I even turned up the main discharge pipe 'upside down' to get a higher level of water in the tank. It must have about 170 litres in there. Cannot go much higher without overflowing....
Still it is working and thats the object of it all.

Water Testing

Just done a quick test. Ph looking steady. No2 improving. No3 the same.

New Air Pump

My old air pump finally gave up. Have been using it since the start in Siam Lake View so must be 4-5 years old. The rubber in the pumping mechanism has perished. At 130 Baht for the pump its done well. But today as a replacement I bough a better one. Has 4 outlets and can do up to 30 litres per minute. So two outlets into top tank and two below. Doubt it does 30 litres per minute under the pressure of being in the bottom of my tank but it does give far better air then previously.  WIll monitor progress.

Water Testing

Just tested the system again for Ph, NO2 and NO3.  No real change but all looks OK?......

National Developments

Things here in Thailand are moving forward.  I've just joined "Association of Aquaponics Thailand". Lets hope we can develop this into something useful.

Sunday Progress

Nothing much of interest to report.  I've left the testing to give it a week to settle down. Don't want daily bad news anyway....

Two more dead cat fish in the sump tank. Not so surprised as there is little nutrient but a lot of crap in there. Again I'll leave them for now.

In my concern for more veggies I have added in some Paw Paw I found starting in the garden, also some onion cuttings and some herbs again from the garden. Should help the plant side a bit.

2 Dead Cat Fish

Had two cat fish die on me last night. I know the Nitrate  and Nitrate levels are extremely high but have been hoping to weather the storm. I've started off some seeds in grow beds, peppers, Bak Choi and Corriander also added in a few small plants from the garden.  I know, I know I should have taken my time and got it established before adding fish but...... We'll see how she goes.
