A Few Questions About Java Moss

[b_evans06]

Sorry if all these questions have been gone over before but I need all the answers in one spot so I can look back and have all the information I need. I have a 20 gallon tank with 1.5wpg. I just bought two bunches of java moss each the size of a golfball. I will be using plant fertilizer and light. Im going to try to grow a good amount without co2. My questions are:

-How much roughly will I be able to grow with just light and fertilizer?
-I read about using the hairnet and laying it on a rock or bogwood. What all is involved to get the moss to spread out to other rocks to form a cover?
-Also will I need to trim or cut it back or will it grow fine without trimming?
-I have a powerhead with the air tube hooked up blowing bubbles into the tank. My friend told me that if I get enough plants that I wont need to add oxygen. Is this true and how will I know the right amount of oxygen to match the amount of plants in the tank.

Thanks for any replies or comments left. If you have any other information to add please feel free Id like to know as much as possible about the plant to make sure it thrives in my tank.

True, but you can still find ALOT of beginner info by searching.

-How much roughly will I be able to grow with just light and fertilizer?
There is not mathmatical equation that we can use to tell you how much you will grow, my guess is give it a month and it'll probaby double in size.

-I read about using the hairnet and laying it on a rock or bogwood. What all is involved to get the moss to spread out to other rocks to form a cover?
-Also will I need to trim or cut it back or will it grow fine without trimming?
You put the moss on the wood/slate, tie it down and wait. Over time it will kind of "root" itself on the wood. Id doesn't stick to rock.

-Also will I need to trim or cut it back or will it grow fine without trimming?
It will grow fine without trimming, but if you're trying to create a Java Moss carpet you will end up trimming it. It grows just as much vertically as along the bogwood/slate.

-I have a powerhead with the air tube hooked up blowing bubbles into the tank. My friend told me that if I get enough plants that I wont need to add oxygen. Is this true and how will I know the right amount of oxygen to match the amount of plants in the tank.
You don't add oxygen for plants, as a matter of fact you want the exact opposite, CO2. Just think about it, humans take IN oxygen and produce CO2, plants take in CO2 and well you get the rest.
