I dose 100ml per day of both calcium and alkalinity and my salinité does not rise at all. I have a top off system with RO water and the water I use for my Bulk Reef Supply 3 parts dosing is also RO pure water.
My salinity stay exactly the same, even after 6 months of dosing daily.
How can dosing calcium and alkalinity in pure RO water cause an increase in salinity? Salt creep usually does the opposite and make you lose salinity over time.
Also what are you using to mesure your salinity? Is it possible that your instrument is going out of wack? Some refractometer have temperature compensation but some don't, so if you are now testing at a different temperature or if your refractometer is not well calibrated, it could give you false result.
I am also surprised that you have to dose so much calcium with the BRS 2 parts in a 55 gallons...how many clam or sps do you have? That seem high.

I'm surprised as well, but here is a FTS to help show how much sps & 2 clams slightly larger than a large fist, are in the tank. As for the 2 part contributing to increased sal. Refer to George's pic. The levels have all been stable with this dosing until only recently & there is no signs of precip in the sandbed, on heaters, or pumps? I can only assume that it is being consumed by the corals, even if I adjust levels mid week by supplemental dosing they fall again by weeksend?
