What is something everyone should try once?

[Gumbies R Us]

We all have ideas, methods, and livestock that work best for our needs. I am wondering what is something you recommend everyone trying at least once with their tanks. Maybe it is a specific equipment that has worked wonders, maybe it is something that you dosed in your tank, or maybe it is simply how you manage a specific aspect of your tank. Curious to see what everyone says!

Co2 scrubber on your skimmer.

Use a recirculator if you've got a float switch.

Algae scrubber
Everyone should have one
Game changer

Here is my tank at two different times, never needing any water changes and never having nutrient issues or algae issues. The sps was about a decade ago with halide and t5, and lps tank is present day and doesn’t use a skimmer, no water changes in 2+ years

Both systems primary filtration was the scrubber
