Oxygen bubbles

[George Farmer]

Since I've added more lighting (from 36w to 76w), and accordingly added more plants, co2 and fertiliser to keep the equilibrium, I'm getting streams of oxygen bubbles from most of my plants. I have a 125 litre (34 US gallon) which gives me less than 2w per gallon, is this normal? I assume it's a good think too?

Pearling: means that all is well with your tank and that things are in balance. I got it fairly frequently when I had my DIY CO2 rig going, but I decided to break that down for a while and since then pearling's only been intermittent. *sob*

Are there plants that aren't pearling?
