Hey guys,
I am very much a novice to the planted aquarium, but I am absolutely loving setting one up. I have created my own yeast bottle which is happily bubbling away and fed it into the intake of my cannister filter, so I am getting some nice fine bubbles that are hanging around the tank for ages before hitting the surface. I have a 95 litre tank (say two and a half foot tank). Can anybody tell me if one two litre bottle is sufficient for that sized tank or do I need more? Thanks all.

I would suggest a second 2 liter bottle for that size tank (about 25 US gallons??). Alternate when you refresh the yeast mixture on each one, to keep the co2 levels as consisitent as possible.

I have two 2L bottles, feeding just 70L of tank. I'd say 2x 2L would be the absolute minimum on a 95L...

As chicken said, alternating each bottle week to week is the way to go...
