I gave up on mine it was more hastle than it was worth. Refract is easy enough. Unless you have a bunch of salt creep salinity fluxuations should not be a issue. The salt stays for the most part and your just topping of fresh water. I cant even remeber the last time I had to make a salinity adjustment.ive got one of those salinity meters from pinpoint, and i noticed that the meter fluctuates often. do u guys own one of these? i calibrated with the solution and backed it up with a refractometer. when i sit the pinpoint in calibration its steady 53mS. when i stick inside the tank it would start fluctuating. could it be flow, or temp causing it? it sits midway towards left side of aquarium...just curious
also, ive been running my skimmer wet and noticed that my salinity would dip a little from the automated kalk reactor topoff. how do u you guys combat salinity fluxuations in your display tank?
