If a question of moss arises and you don't know what the answer is what should you do? Call me, your friendly (usually) neighborhood Moss Man!
Well yes, plants working as your "bio-filter" so to speak generally holds true if you have lots of fast growing plants. Moss I personally don't think of as a plant that would be considered to be a part of that group. It is better than nothing though, but it is so slow growing. But, if it is able to soak up the ammonia, etc. then that's golden!
Either way, 3 danios does not seem like too much for a 5.5 gallon tank.
What type of algae is it? Got any pictures you may post? Often times new set-ups may run into algae problems like diatoms, etc. that may go away just with time.
Sorry to put it so flat and bold, but you're wrong. Want photo evidence? Here it is. This was in about one month, no ferts!
1 or 2 months growth not too sure
I had the same problem. I think I know.
Moss do fine in low light, no nutrient situation like a bucket.
But when you put it in an aquarium with decent lights, some nutrients, algae will grow all over it... The key is CO2... When you give plants light & nutrients but no CO2, it won't do so well.. So, the algae will use what the moss is not using.
Yes and No, Usually talking you give plants CO2 to suck up nutrients faster than they would with the normal CO2 levels in the tank, thus pumping the tank water with nutrients and CO2 to make plants grow much faster than normal. Moss requires no CO2, I don't think it really cares too too much either way. Yeah it will help but it's not required. The key thing is light, there is too much light and too little plant mass. If you want to keep the algea at bay you need to up the plant mass. Simple as that
Any more moss questions PM me since I might miss them here.
PS. I know some people will think I'm a bit high on CO2 right now, but all the stuff stated is quiet true... but I'm about to fall asleep and should be doing homework so It might be a bit off.
