Is reef keeping hard?

[@comment.highlighted]

I do a 20% water change every week because I can see my fish and corals act livelier 🙂

Everything always seems happier after a water change.

I was doing 50% water changes every other week and I think it was shocking everything so have since changed 20% weekly.. will see how long my will power lasts 😂

50% is alot. I've seen people successfully do it. I like to be around 20%
