I guess more or less the algae problem is due to the high in NO3. Over the last few months, due to laziness, I neglect this tank and fishes all one by one death, I did not change water as frequent as before. Last week seek help to do a clean up and stock up some fishes , corals...
Yesterday I do a tap water with sea salt mix 25% change of water and do a check, NO3 still very high
The API I have added in twice, but did not do the job. Look! I got so many tang, don't seem of great help also
Will cheato be a good help?
Anyone or where I can get it from?
Thanks
