Since you were recently out of stock, I gather that this is the new batches and all the old bad batches are not being sold
Question by: Floyd Elder on Feb 4, 2016 9:58:00 PM
Great question! The batch of reagents that we have now were inspected by Hanna Instruments and passed, meaning there is a possibility that the batch number will still match the recall, however they have been approved by Hanna before they were sent to us. Any reagents with a batch number that matches the recall will have a small green "pass" sticker, indicating that Hanna has approved them for use.

Does this reagent work with the new HI772 DKH Hanna Checker?

  • Great By reddog on 11/17/2016

    Great refills for my Alk checker. I use this alk test almost exclusively.
  • GOOD STUFF By TWang on 10/31/2016

    These reagents are not expensive at all. Like one other user said, i wish they would come in a bigger bottle. The only complaint i have is the blue cap on the bottle always stains my fingers. Whats up with that!
  • Good W/ Clumps By TheReefTankGuy on 10/18/2016

    Gives me accurate reading but always has floating partials in it. I'm not sure if that's doing anything for my readings though.
  • Hanna HI755-26 Checker Reagents By Chuck on 10/7/2016

    I like the Hanna system for Alkalinity and Calcium
  • Does what it is suppose to By DBR_Reef on 10/4/2016

    Mine always has clumps in the bottom- not sure if it's something to worry about- it seem s to work fine
  • Bottle way to small By jose on 9/8/2016

    Would be better if the bottle was bigger
  • As expected By Jason on 8/19/2016

    Works as expected. The alkalinity checker is awesome. This is the reagent with a decent price point. I refuse to give it 5 stars because it needs to come in a bigger bottle with a bulk discount. 25 tests just isn't enough to stop me from ordering it again a little too quickly for my taste. Especially if you're in a position where you are figuring out your dosing regiment and test frequently.
  • Hi755-26 alkalinity checker reagents By Chuck on 7/7/2016

    I have always had good luck with this product
  • Very consistent readings By Steve on 7/3/2016

    I've been using Hanna's digital water analysis methods for years. I've used the Alk test for 4 years now. It is fast, easy and consistent. If I assay the my tank water 3 times in a row, all readings are within 4 ppm (consistency). I am following Ryan's advice and assaying Alk daily because it is so affordable. It has enabled me to diagnose two problems over the past 3 months (dosing pump line clog, CO2 reactor drip slow-down).
  • An Essential Test, And An Essential Reagent By Richard on 6/6/2016

    I have three of the Hanna checkers: alkalinity, calcium, and phosphate. I couldn't do without all three! Totally eliminated is the need to match colors and interpolate results that are between colors. The testers come with sufficient reagents for about 25 tests, so the replacement reagent sets are a necessity. BRS carries them all at a good price. It's simple: the alkalinity set includes the reagent bottle (25 tests) and a new 1 ml syringe. That's it. Try them and you'll never go back.
  • love it By mquinn1 on 5/6/2016

    Quick and easy
  • Nice product By Anirban on 5/4/2016

    Consistent and comparable readings and quite fast sample processing.
