Re: [APD] How much light is too much.

You probably have enough light now. What kind of
bulbs/ballasts are you running. More than 3 wpg is probably
too much unless you are taking special care to adapt. You
can add more light but you will need to add more nutrients
so that the plants can make use of it and then prune more
often to keep them from getting out of hand. Your tank will
probably need daily attention if you add much more light
than 3 wpg.
