  1. Best way to test for salinity

    Posted by Unknown on Apr 23rd 2018

    I have a hard time reading a refractometer and the constant calibrating lead me to this product. Very happy with my purchase. Makes testing so much easier and the readings seem to be on point.

  2. Throw away the hard to read Refractometer

    Posted by Reefkpr on Apr 23rd 2018

    I have 2 Refractometers and 4 bottles of calibration fluid. Always get different readings. This makes it difficult to test 3 tanks. Purchased the IceCap and couldn't be happier. Now all my tanks have matching Salinity. Like a few others have reported, I find I get a better reading without using the rubber cup on the end of the IceCap.

  3. Simple and Easy!

    This is a great product for quick testing of salinity, especially if you have multiple tanks. I took reading from two takes I have at home and they matched previous readings I took before with a refractometer I recently recalibrated.

    All I had to do was press the button, dip the sensor in my tank and wait for the beep. Then the LCD lights up to show you the SG. Cleaning is a simple rinse the sensor over a faucet, dry, and put away.

    I find this device great because I also have a water station outside and I can just bring the meter out there without the dropper (which I loose often) and wait 30-45 seconds for temperature compensation, and then get some good light to look through the telescope (I wear glasses)---heck! This thing works in pitch darkness!

  4. Yes, you need it!

    A very cool little gadget. Quick, easy and spot on with my refractometer when it comes to accuracy. Nice to know the temp as well, especially when you're adding recently mixed water. Get one.

  5. Great tester

    Posted by Dylan on Mar 30th 2018

    I’m getting older so deciphering the line on my refractometer was getting tough. My kids also broke my refractometer so I needing something new. Came across this at Fragniappe in New Orleans at a great intro price. It’s amazing! Compared it with my refractometer and it’s dead on without error of eyesight. The fact it also reads temp. Is a plus. Only thing I’ve noticed is I have to test 3-4 times in a row to get stable temp. Readings.
