    i have a 1ft tank with moss..without co2 and liquid fert.. moss is growing very slow.. is it advisable to buy some liquid fert and used a little for every water change?
    my fren told mi that even putting liquid fert into tank without co2 will not grow well cos all the nutrient is gone.. is it true?

    Let's use some logical thinking...
    Our aquarium is a closed system. So if there is nothing taken out, where can the nutrient disappear to? Either it has changed to some form unusable (meaning it precipitated) or absorbed or adsorption by something...

    So in short, what your friend said is not very true...

    But, there is some truth in what ever your friend has said is that, excess nutrient will do your tank no good but more harm as without CO2, the plants will not be taking in the nutrients available... Harm in the form of algae...

    Think this as building a barrack in a strategy game... You got all the lumber but no stone... How you going to build? The stone becomes a limiting factor... Same for building cells in plants, no CO2 for carbon, got nutrient also no use...

    A drop or two is sufficient in your case once a while as CO2 will still be diffused at the surface of the water... And your fish will generate some CO2 too...

    Hi,

    Just sharing some info that I have picked up from other forumers. The most important factors for good moss growth are:
    1. Water temperature (<28degrees C is good)
    2. Good water circulation

    Moss do not require liquid fert but who is to complain with an extra boost of nutrient? Don't overdo the dosing and with high lighting, you could be inviting a host of algae problems. Moss also use another form of CO2; bicarbonates if I am not wrong, so there is no need to inject CO2 into the moss tank.

    Perhaps other forumers could help you with more pointers on growing moss. Good luck!

    Moss do not use bicarbonate as a source of carbon. They only use CO2. Note: Moss do need nutrients but if you go low light and non-CO2, the moss like all other plants will down regulate their photosynthethic rate and hence less need for high CO2 and nutrients. (Not none needed...just lesser.).

    Hi, can explain what's bicarbonate in layman/non-scientific term? Is it organic carbon?
