Perhaps a silly question. Perhaps not?

My pond is several years old.

Never any fish.

Should I still test/monitor water chemistry?

Soft city water. haven't needed to add water in over a year. Good flow, plenty of aration from waterfall and stream. Plenty of plants.
Just no fish!

No need to test if you don't have fish!
