Re: Very high light for 20 long
I feel strange being on the other side of this 'conversation'...
IME, I see no reason why 99% of the available plants cannot be grown with a single t5ho bulb 2" above a 20L.
Instead of blindly dumping more $$ into a new fixture, you (and all of us) can benefit from figuring out what is going on.
I would start by taking a picture of the label on your t5ho bulb and posting it. That would give all of us a place to dance from. If the type/brand/temp/age/etc is not totally out of whack, then I would contact Catalina to find out if they, by any chance, installed the wrong ballast or cheappo reflector.
That aside, posting several pictures if the plants that you are not happy with, plus full tank shot with drop checker, would go miles to putting this thread to bed.
Telling what your lighting period is, you fertilization and other basic info would not hurt either.
