Quick - Before my whole tank Dies

i know its too late, but i don't think i can lighting lighting lighting enough. If you plan on getting another one, plan on at least 3 watts per a gallon (although this isn't entirely accurate). I got an LTA (in complete ignorance) and when he started looking like a pile of crap i immediately bought new lighting (T5's). That was 6 months ago, and he looks better than ever! I also hear you should not get one until your tank is a well established system (at least 6 months to a year old i think?, probably older), although i did not follow that one. Got lucky i guess

 

In a 20 gallon system with my Power Compact 65 watts -

Do you think a LTA can live.
