I have looked everywhere for this answer to a problem i a having and nobody can answer it for me.. I have a 90 gallon reef tank. everyday my alk goes from 9-10 to 4-5, i have to add baking soda daily to keep it up. My calcium levels drop the same way daily. When I add baking soda,or calcium i get these white hard to remove streaks on the glass, i have to manually scrape it off with a razor daily. for it to appear again a few hours later. I do weekly water changes using reef crystals my magnesium is at 1400. what is causing these streaks and why does my alk swing so much along with the calcium?

What salinity is the water?
My first guess is that one of the kits is seriously off and alk, for example, may be a lot higher than you think.
