Thanks Yeanchon, for the reply. well, i am running 2x 25W FL light.Actually It came together with the light I bought, Resun is the name. It has a switch to either go for a single FL or double. I am not sure if its too much for my plants. So far by the looks of it my plants are OK.

As for the PH And Kh reading, what do you recommend. Actually I am still looking for some crypt fo my foregnd, any idea which LFS have those.

I have stop using the Nutrafin, instead I been using the diy CO2 attched to this revolving bio-balls. My nutrafin did not work out, I am not sure why...after >24hrs waiting for the bubbles nothing happen decided to go onn Diy, and its working great.

Rgds.
