I have just switched on my Co2 system for the first time and wondered what would be a good bubble count to kick off with? The plants arrived this morning by post and I have them floating in the tank. According to the instructions that came with them I should not seperate the planlets and plant for about a week! My tank is 48"x24"x24", lighting is 4 x 54 watt T8's, ph 7.2, 0 ammonia, 0 nitrite and 60 nitrate and no fish yet. Also should I start to feed the plants imeadiatly and if yes what should I use? All advice will be much appreciated.
