Hi, i have a 40cm cube which is 13im gallons and im currently running a 11w light, i feel this isnt enough and i am looking to upgrade, i have been browsing and i have found http://www.aquatics-online.co.uk/addtobasket.asp?skid=7357&retp=794&rets=188 i know its abit more power which is good, but it also gives me the option to double up for even more light b ut my main worry is the evaporation, as the tank will have no lid, how much water will be lost through evaporation? would it be enough to worry about.
Also will the amount of light give me enough to grow most plants like hair grass and riccia succesfully?
