It had been four weeks since the tank was setup. Plants have grown very well with lush green all the time. There was very minimal algae issue happened in the tank. Since the the tank had no fauna, I increased the CO2 injection rate to 2bps for 8 hours a day. Lighting time also increased to 8 hours a day, started one hour after CO2 injection begin and ended one hour after CO2 stop.
First trimming for the right background of Heteranthera zosterifolia (aka Star Grass) was done since the branches grew very fast and touch the surface water. I trimmed it quite short to created bushy effect in the future.

Eleocharis acicularis 'Mini' had been growing well, too. Its roots started to spread in wider area and slowly covered more space on the foreground. I used 2 tubs of 1-2 Grows! Eleocharis sp. 'Mini' for my 2ft tank at the beginning, so the covering speed was also faster.
