great product By GT-Reefer on 3/7/2013GT-Reefer would recommend this product to a friendI use the 7 and 10 and it works great. I pre rinse my probe in RO/DI, then start my calibration, but I will start using a little cal fluid to rinse away the water for a more accurate calibration.
Exactly what you expect, shipped lighting-fast by BRS. By Chuck on 8/13/2012Chuck would recommend this product to a friendThis product works great, is very competitively priced, and I like knowing when I order items like this from BRS they'll arrive within a few days without hassles or delays. I'll definitely be getting more from BRS when I need them.
Worked like it should By Andy on 8/1/2012Andy would recommend this product to a friendWorked nicely to calibrate my pinpoint probe.
Worked like it should By Andy on 8/1/2012Andy would recommend this product to a friendChecked it against some other calibration fluid and it is dead on.
Cheap and easy By Matthew on 2/22/2012Matthew would recommend this product to a friendNeeded the 4 and 7 for my RFI pH controller. Easy to use. I've heard that some people will rinse the probe in some of the solution and pour the rest (3/4 or so) in a tall shot glass to make sure the probe is clear of water or other elements.
Does its job at a great price By Greg on 9/23/2011Greg would recommend this product to a friendDoes what its supposed to at a great price. I put 3/4 of the packet in a tall skinny shot glass, and use the other 1/4 of the packet to "rinse" the water off the probe (after already rinsing in clean or RO water). Then I can let the probe stand up in the shot glass without worrying about a packet falling over.

I noticed in reviews for the ph calibration, comments about storing the ph probe in a shot glass etc. Are you supposed to do this or can it just stay in the aquarium it's monitoring. Sorry if this question seems illogical, I am new to the controller concept and have one on the way. Thanks,
Bulk Reef Supply Hey James,
If your going to have the probe out of the tank for a long time you don't want it to dry out, so it should be stored in a probe storage solution. As far as calibration itself goes, most of us just open the top of the calibration solution, submerge the probe in the pouch and follow the controllers calibration procedure.
Each, highly accurate, packet of PINPOINT pH Calibration Fluid contains ample fluid for calibration (about 30mL).
- PINPOINT pH 4.00 is accurate to +/- .002.
- PINPOINT pH 7.00 is accurate to +/- .002.
- PINPOINT pH 10.00 is accurate to +/- .005.
All electronic pH instruments should be calibrated monthly.
