Thanks everyone, we don't have phosphate testers in my neck of the woods; also no brown algae on the glass only good green stuff. I really like my fish; even if they are messy but I have cut down on my feeding; maybe feeding too much; there is some new plant growth, just not much. Tried making a homemade co2 generator using a 2 litre coke bottle yesterday, isn't working yet but they say it might take 3 days to get going, anyone have any info about them; they work, they don't? The web site where I got info from says they do? Don't have a lot of money to spend on the tank, so am trying to make what I can. Anyone have any more ideas for me to try?
I figured from what was said that if I did a water change; did that two weeks ago, my ammonia is perfect, so is my nitrites that I might make the brown algae grow more?
Thanks for any replies.
