In 2019 I got sick had a 120 gal saltwater tank. Well of course I had to get rid of it. Almost two years ago I got another one this time it 90 gal saltwater with a sump. a couple of weeks brown rocks, salt way to high, and bad salt creep. Thought it calibrator. So I tried refractor meter. Still high so I been putting filtered water no salt. Trying to get down no luck yet. Any advice wo be greatly appreciated.
