Is this light too much for a Low Tech?
I bought this for a 20 gallon high, I have found some PAR stats in here but not for this light on that size tank. What do you guys think? I am just getting back in the game and basically new to how much tech is available these days. I have two 20 gallon high tanks, I want to do one "low tech", then one "high tech" then I have a 55 to do when I have a little success. Thanks in advance.
