How many bubbles per second?

Hey all,
i have 55 gallon planted aquarium that has 1 amazon sword, 5 stems of hygrophila, 8 jungle vals, 2 bunches of moss ( i believe one bunch is spike moss the other bunch is Christmas moss), about 20 stems of pink rotala, 4 stems of bacopa, 2 stems of temple, newly planted monte carlo, and about 20 stems of macaya. i am wondering how many bubbles per second I need for my aquarium. I am currently doing 2 bubbles per second and am starting to think that 2 bubbles per second is not enough for my aquarium, since my monte carlo, that was in the aquarium for about 2 weeks is not growing. should I add more co2 or leave it as it is.

Other than this what is optimal water parameters for the plant, temple? I have had them in my aquarium for about two months now and had over ten stems at the beginning. I have been losing stems since then and have only had two left. these two stems are doing fine, so far. the water temperature in my aquarium currently is 23 degrees Celcius. the reason why the temp is so low is that i live in Australia and it is currently winter.

Google says Temple plant is Hygrophila corymbosa
As for bubbles per second, 2 is nowhere near enough for good CO2 levels even with the most efficient dissolution
I would continue up'ing it gradually until you see visible pearling on your plants, that is assuming your light is sufficiently strong

Do you have a drop checker? it should read green.
What is your fetilizer dosing regime?

The Temple Compacta plant was one of the first ones that I put in my Nano tank. I had 4 stems that were about 4" tall. Within three weeks they were 11" tall and starting to bend over due to being out of the water. I trimmed them to 8 plants and they kept going. I probably have around 16 in my tank now but gave some away to a fellow planted tank keeper.

As long as they have fair lighting they should be doing great.

How about posting water specs and tell us about the lights you are using. The max temp my tank got to was 75* so I don't think temperature is an issue. I would suggest a drop checker as well, as I have CO2 on my tank and have yet to see pearling with my plants. I actually stated getting to much CO2 and all I saw was my fish swimming at the top of the tank due to having too much CO2. It's not nice to see your fish suffocating like that.

A picture of the tank might help also.
