There are people that keep tanks at 37ppt. I mean, this definitely doesn't help, especially if corals weren't properly acclimated to these levels.Ok so here goes nothing , could this be the culprit?
Well, they are in that tank for a while now, last coral addition was maybe 6 months ago... And I always check salinity the same way. I guess the screw did go off slowly.There are people that keep tanks at 37ppt. I mean, this definitely doesn't help, especially if corals weren't properly acclimated to these levels.
Hanna digital checker. Calibrate it monthly. You'll be all set!Well, they are in that tank for a while now, last coral addition was maybe 6 months ago... And I always check salinity the same way. I guess the screw did go off slowly.
Indeed top off is automatic with an osmolator dosing Reversed Osmosis.It's a bit on the salty side but not drastically so. There's probably a surprising number of tanks on here doing fine at 1.027 for a variety of reasons. I'd SLOWLY steer it down to your target level over the course of a month or so but wouldn't worry too much about the salinity. All the signs right now point toward the livestock being stressed by drastic parameter swings and the last thing you want is to have that happen again.
You can dial it down by just doing your normal water change routine, assuming it's not too aggressive. Or by doing like a cup a day pulling out salt water and replacing with RO water. Just to verify though, you're topping off the evaporation with RO water, and not salt water, correct?
Right now I'd say wait a day, don't touch anything, and do a full batch of tests tomorrow and report. Then we can help steer you appropriately based on your numbers.
If you have the tests, I'd like to see these numbers at minimum
ph
kh
calc
mag
temp
Less critical in this case, but I suggest also nitrate and phosphate.
Like I said in another post, I am using a refractometer, the plastic one has been used like 5-6 times overall haha. I just double checked my refractometer with it.Also ditch that outdated thing and get a refractometer, they are quite cheap and daft more accurate then those old swingvarm hydrometers, plus a refractometer can be calibrated.
