Water Changing

[craig-s]

well my tank has been running now for a few months,the fish are settled,bacteria has built up in the filter,and the water is looking great,fish and plants look beautiful,the wait was well worth it,now heres the question,i do a 10% water change weekly adding stress coat and stress zyme at the same time,is this OK,do i need to change the water completely at any time,or is the 10% sufficient to keep the aquarium looking good?

You should be fine. The main purpose of water change is to lower nitrates and so you can do a gravel vac to clean up waste. As long as your water parameters are staying where they need to be, 10% is fine although most people usually are in the 15 to 25 percent range on sommunity tanks.
