i recently had to purchase a refractometer as well as i had been using my hydrometer, which was reading 1.025, but as it turns out it was out by .004 even after using the correction factors. so it was actually 1.029. no wonder my fish were stressed. all my corals had no problem though. xenia was pulsing like mad like it always does.
