well ive been told to have 2 watts of light per gallon in your tank, if you go over this algea grows fast and its just generally not good.
for my 1 tank which is 18- 20 gal, (not sure exactly) ive got a 20 watt and my plants arnt doing too well ... so should i upgrade to a 40 watt or higher?
(just tell me straight if im being totaly dumb
