Testing revisited

After many years, we still don’t test. We don’t worry about nitrates, nitrites, phosphates, salinity and on and on. The theme is keep it simple and keep easy-to-keep fish and corals to begin with.

Everyday, we observe the tank. How do the corals look? Do the fish look and act healthy?

Do a simple “white sink” or bowl test. Is the water clear? How does it smell?
