Ammonia - too many water changes?
Kept an aquarium years ago, but when I moved new owner took over. Several weeks ago I bought a 7 litre betta haven for one! I kept it for a couple of weeks with just water and bio treatment. Fish shop said water ok so bought fighter. Iíve had him a week and heís obviously not too well. Iíve bought a water test kit and awful high ammonia reading. Is it ok to do a 10% water change every day. I think there is a slight reduction in reading today. But donít want to kill him with too many changes. Read up on the damage Amonia does so not optimistic on his survival.
