Want to stretch out Wc’s. What are the bad signs to look for?

Currently doing weekly 20% water changes. Want to try doing biweekly 20% water changes to save time & money. What are some signs to look for to tell me my tank is not happy and that it wants weekly water changes? Thanks in advance

Depends on your size and what inhabitants you keep. As for me, I’ve stretched my WC routine for almost 4 years now. The tank is a SPS-dominant 159g cube! I got a CaRx and a skimmer — that’s pretty much it.
