Look how thick Micranthemum 'Monte Carlo' growth without sign of yellowing at the bottom. Unlike my previous favorite carpet plant, HC.

IIAC (ISTA International Aquascaping Contest) 2015

New international competition from Taiwan (http://www.iiac.com.tw/index.php).

Very promising event, it could even be better that IAPLC. Judges, scoring method and prizes are already better than IAPLC. There are 13 Judges, all top scapers around the world unlike IAPLC judges who some of them don't even know how to scape. Submission open 1st February, close 31st July. The interesting part, it is accepting 5 works for each participants unlike IAPLC only 1 work per participants. Another interesting part is the scoring method, the highest and lowest score will be deducted and calculate the mean as final scores. The result will be announced 1st November. Lets see how it goes, looking forward to it.

Very promising event, it could even be better that IAPLC.

LED Floodlight For Planted Tank

Using 20W LED floodlight for my 1.3ft tank. It is very easy to do, everyone should be able to DIY, just need to extent the wire to the wall socket. On second thought, I should not classify it as DIY :p

PAR reading for various light on the same tank:
20W LED 15cm from water surface.
- 1cm above water: ~201 umol
- water surface: ~169 umol (sensor fully submerge)
- 20cm below water: ~66 umol

6.5W LED WEIPRO 7cm from water surface.(120 small LED inside)
- 1cm above water: ~67 umol
- water surface: ~55 umol (sensor fully submerge)
- 20cm below water: ~18 umol

55W PL Aquasonic Fluorescent 7cm from water surface.
- 1cm above water: ~267 umol
- water surface: ~244 umol (sensor fully submerge)
- 20cm below water: ~76 umol

Comparing all 3 lights, WEIPRO 6.5W LED is pretty much useless for planted tank. I surprise ho fast the PAR reading drop on the Fluorescent light, at the bottom surface it is pretty much same intensity as 20W LED. It is not practical but just for curiosity, I measure 7cm under 20W LED and PAR reading was 558umol.

You can also do something like below which my friend did on his 3ft tank
