Salinity 31.5ppt

[brownsalt92]

I check saltwater with my refractometer it says 1.025 but I just hooked up my new apex and it reads 31.5ppt or 1.0237 should i go with apex salinity number? It's probly human error with my refractometer

Have you calibrated the Apex probe? How about your refractometer?

I'd keep things stable for now, and gradually adjust as needed after you've calibrated your gear.

Yes calibrated my apex probe it read 34.99ppt when I calibrated. Refractometer is probly off I haven't checked my refractometer in probly 2 weeks for sure corals look happy except for a new chalice I got on monday.

I've had problems calibrating the apex salinity probe before. Do you have standard sea water solution? If so check both of them with it. If not, I'd calibrate the refractometer (is it electronic btw?) And trust that one... In the meantime I'd order standard seawater 35ppt solution (from brs for example) and check both against that.

From my experience, as you can tell, I'd highly favor the refractometer...

I have 35 ppt solution in my.cabinet last time I used that on my refactometer it tested 1.027 so it should be accurate I will test tommaro refractometer and my salinity probe, narrow it down. When I calibrated the refractometer the last time.woth solution my tank read 1.025 on refractometer, lfs said it was 1.027

+1 on the standard seawater solution. I check the calibration on my refractometer before each use. Just for the peace of mind. Try not to do anything rash until you know exactly where you stand.

Alright I will replugged my ato back in, test tommaro after work! Thanks for imput

Well I added no salt and it went from 31.5 ppt to 34.1 ppt today.

I got many text alerts saying my tank was 83. My chiller said 80 it's a arctica chiller on my 90 DT. I checked my tank with a thermometer my wife had and a infared thermometer which says sand bed is 83 degrees and rock work towards the top of my tank is 84 degrees. Can my chiller really be off 3 degrees?

My ph also reads at 6:15 am is 7.8 and right now 8.44 with water at 83 degrees I will double check with a test kit but is the ph probes that accurate? Is 8.4 okay for my tank? Mainly sps

Have redundant kits for everything when you start. My apex probes don't stay calibrated very long. Neptune was great at helping me but my salinity probe stinks. The apex ph probe is better but still jumps occasionally.

After awhile you learn which ones to trust and what is suspect.

I have a Milwaukee salinity monitor, a Seneye, an instant ocean SG device and a Red Sea spectrometer. Pretty much all are close except the apex (only stays calibrated for a few hours)

For ph I have the apex, Seneye and Red Sea test kit. Two are pretty consistent...

For temp apex, Seneye and some floaters in places. All pretty much match all the time here.

For wifi... I use apex and Seneye. The Seneye always works and I have to restart the apex 2016 quite a bit. I know I have a lousy network in my house as it screws up my TiVo too but the Seneye keeps lit and transmitting.

I love this apex but I find redundancy is saving my bacon with my new setup

Thanks terry! I tested salinity probe it was actually spot in now
The ph is reading right I tested with 2 different kits
Temp was on point also besides for my chiller display is off for sure 2.3 degrees
I adjusted accordingly on chiller

My salinty probe is off some. I trust my refractometer. But with a correction factor the probe seems stable. My temperature probe seems reliable also.
