Firstly I have to apologise to all that following this blog for not updating my progress.
This year fasting month's really take a toll on us here, unpredictable weather and the H1N1 flu makes matter worst.
I will be a bit slow from late August till end September.
I bought a new camcorder, one of those "youtube optimised ultra cheap don't waste your money" kinda thing so that I could make better video on Aquaponics. Look forward for the right moment to use it.
Tomatoes and chillies got infested by "White Flies" and I had to destroy them. Stop growing them for a while to get things stabilized, meanwhile I plant herb like mint, basil, coriander and others.
Photo above are those Basil, this I do from cutting so does Mint below. It still in patches here and there.
Fern don't need an update.. they are wild... :) 
The Tilapia doing great, they grow very fast and no more fatality with the young ones. In a month time they should be palatable.
Water PH just check yesterday at 7.5, look like its stabilized at that figure. I've drain some water out due to it rain almost daily and high water may cause insufficient oxygen. The water flowing out from the siphon outlet just not high enough to cause a good mix.
As I mention, it will be a bit slow this next few weeks. My home kit not assembled yet, that will be done later.
Cheers.
Last did PH test was about a month ago, its been raining these past few days. Water condition high in the tank I have to drained out to maintain a comfortable level for siphon to work.
Plants not doing well due to wet condition, I am replanting the tomatoes and clearing the beds for different plants.
PH tested its on the high side about 7.5, I need to monitor or best pour some vinegar to adjust PH value.
Grow beds need to be raise about 3 inches, to ensure high water did not cover the siphon outlet, this can be done by putting bricks underneath the grow bed support. Only problem its too heavy and need to be emptied before I am able to lift it up.
Its now coming to fasting months over here, and most activities will be at a slower pace. I'll sow new seeds, get some Mint and Basil cuttings.
Tomatoes, not that encouraging. There are few fruiting, I will need to try different variety. Over here most tomatoes are grown in the highlands where its cool and more sunshine.
The right variety will do well, I grown tomatoes on soil before and they do well. Its a challenge now to do it Aquaponics. I have a seed package will try that one next.
These particular tomatoes I use fresh tomato from the supermarket and sow them, so their origin may be different from what I wanted.
The growbed was new and haven't cycle or mature, I do not want to waste a packed seed yet.
There are sign of "White Flies" I don't know what the English name but over here we call it Bena Putih, Putih = White and Bena is the equivalent to Flea,, So "White Flea" if I do a direct translation.
I can't use pesticide, the fish will be affected. There are traditional remedy for this that is totally save for Aquaponics. I'll try to make it and see whether it work, then I'll post the instruction.
