So Ill try to summarize... no let me sum up.
built tank - used rsr450 1/19. 1st build with dry rock PITA. my refractometer was a point of sale. got new "good" one. calibrated with rodi and wemt about my business.
Had nithing but seriously struggled with corals fish always super healthy. chased all kinds of possible solutions- Swapped Lighting, PO4 (lack thereof), NO3 (lack thereof) struggled with getting fuge up and running, instituted AWC, added autofeeder 4x's/dsy to get nutrients etc.. no partucular order there.
Now i have never really trusted the apex cond probe ive read too many issues but it always read low but my refractimeter read 1.026 so i trusted the tried and true. last brs order on a whim i purchased refractometer calibration sol'n. i had to break out the little screwdriver. according to the newly calibrated refactometer my tank was running at 1.022 and has been for over a YEAR! immediately put my ato tube in awc bucket and let it go. after all this is lt turns out the apex probe was right, it now agrees with refractometer that was calibrated with 35ppt solution. Funny thing is when i put in the rodi it does NOT read zero. WHY??? In true old school fashion i started listening to my corals again and as the salinity climbed corals that had hardly opened at all are now fully opened. Zoas that never opened are now. Such an AHAH moment for my tank. Kind of embarrasing given that i have been reefing since 2001 that i was running 1.022 thinking i was @ 1.026 for over a year
