So about a week ago my power went out at work and the filter, heater, and light went off for a day or so...a few fish kicked the bucket but for the next 3-4 days my plants were going INSANE. I figured this was due to all the dead algae acting as fertilizer. I mean the stems to my banana plants were growing 4-6 inches a day! Now i cant get them to grow like that... I tried adding Co2 but Im curious as to how long it takes before you notice drastic growth, also how else can i encourage it. My light bulb is a wayyy too old 20w bulb and for the 29gallon tank its just not enough, I know.. but until I change it what else can I do?
