Salinity? Who is fighting it?

[scmoore2-]

My salinity keeps going up. I have started over after a 19 year run. Tank is cycling still. I used some old rocks. And some new. I keep adding fresh RO water, but I am not adding any salt. All other levels are ok. Phosphates are up a little. Am I over thinking? Im not new to the game, just do not remember it starting out this way.

Thanks

Maybe it’s a measurement problem.

Salinity does not rise unless you add salts somehow, or evaporation lowers the water level.

Salinity is stable adding just ro/di water for top off.
