Great skinny salinity probe

Pros: Skinny

Cons: Maybe too long, doesn’t come with solutions

I’m only giving it 4 stars because it’s pricey but overall, great product and easy to calibrate and it doesn’t come with solutions to calibrate. LAME

Its a must item

Cons: Pricey , hard to calibrate

Works great, but can be a little stubborn when first put into water. Pay special attention to instructions and tips on how to remove air bubbles. You need to also have temp probe plugged into PM2 module for increased accuracy.

APEX Salinity Probe

I have used this probe for 2 years. Twice it did not adjust to drops in salinity due to my own mistake when adjusting my saltwater auto exchange. It finally got to a point were it would not even give a proper reading. I would do a online search before putting much faith in this probe. It might cost you your tank.

Quality probe

Pros: Accurate reading

Cons: Calibration was difficult

it was difficult for me to calibrate with 53,000 fluid.i followed the instructions and set the calibration fluid in my sump to match temp probe. I set temp probe compensation 2.2 and the initial salinity reading was off from my refractometer. It took three tries to calibrate but I eventually got a good reading. As I read in many forums the micro bubbles do affect the readings. Be sure when mounting probes find a calm area.

Does what it is suppose to

Calibration was quick and easy. Conductivity seems to hold pretty stable in a narrow range consistent with what would be expected for evaporation and top off. This helps me feel more confident in controlling my ATO and ensuring my salinity is in a safe range.
