Some people have all the luck. Those small bubble are a good thing. it means everything in your tank is in ballance and don't mess with it...lol. Congrats on the great work you got there.
Thanks for the replies...it was too good to be true though Rose...the bubbles stuck around for a day or two and now they are gone...don't know what happened!!
Re: bubbles no longer around.
Could it be because the nutrients in the water have 'run out', try adding a plant fertiliser. Or perhaps the rate of CO 2 infusion isn't enough and lack of Co2 is the problem, in which case step up the Co2 rate.
I am using a Hagen Co2 diffuser and my lighting is 3 20 watt fluorecent bulbs, Sun glo at the back, life glo in the middle and a regular fluorecent in the front...but will be replaced with a power glo for the front.
