Product Questions


I just have a question in determining the amount of titrant used for the test. So if I start with 1ML and I end with 0.46ML left then I would subtract .46 from 1.0 to get 0.54 titrant used. Then I would use 0.54 as my number on the card to get my results. Is this the correct process?
Question by: Donnie Alderman on Jun 29, 2014 11:41:00 AM
Hi Donnie,
That is correct :-) You compare the amount of titrant used to the chart, so your math looks good to me!

So my question is now that it is winter. Is it bad for this test kit to be exposed to below freezing temps during shipping.
Question by: Michael on Jan 20, 2016 11:07:00 AM
Great question!
These test kits tend to have a lower than normal freezing temperature and typically we have not received much negative feed back during shipments in winter. If you have any issues or questions feel free to let us know and we will be more than willing to help!

  • Great product By Jose C. on 11/14/2015

    At first it was confusing. It takes time getting the correct color in the vale. But with a few practices and some patience it became easy. The videos on youtube were a great help also.
  • Good quality product By Daniel on 10/15/2015

    Good quality product, nicely fits into a hard plastic box for storage, the cards are laminated and everything is designed to last. Everything is color coded so you use the right siringe with each test. Takes some time to do the tests, but the accuracy is worth it, good things don't come easy.
  • Not bad By Paul on 6/28/2015

    Actually, these tests work well, now that my lfs gave me some pointers. Instructions could be better regarding timing of the drips and what to watch for with the color change.
  • Good Kit By RICHARD on 6/16/2015

    The 1 ml titration syringes have different color tips, but I still labeled them to make sure I only use a certain 1 ml syringe for each test. Easy instructions to follow.
  • Great Test Kit By Doug on 3/21/2015

    This test kit is great. It features easy to read results and the test itself is very easy to administer. The one thing is that I wish it had a larger case to keep everything in.
  • Excellent for beginners! By Patrick of Bay Area Coral on 3/16/2015

    This is priced perfectly for beginner reefers. Three very important tests and very easy to perform. Hanna checker is the way to go long term, but if you need a cost effective way to test for CA, ALK, and MG, I can't think of any better test kit.
  • Very nice kit By Dan on 3/13/2015

    I've been using this kit for a year or so and like it a lot. The cons that I list don't really take much away - they're mostly nit-picky. The kit is still very good.
    -very accurate, end of titration is easy to see within a couple drops
    -I like that refills are available
    -Good value for three kits
    -Nice plastic box to hold everything in - good for water environment.
    -Instructions are clear and printed in color on heavy, glossy cardstock - good for water environment.

    -The box is a little small and everything is pretty jammed in there
    -The small syringes work well, but the labeling wears off within a year of bi-weekly use.
    -The titrator handle thing is really not very useful. I'd rather swirl the solution with one hand and add drops with the other so I skip the titrator.
  • Great Kit By Nerdymunky on 2/17/2015

    Can't beat this kit. Very accurate and easy enough to do to keep on top of your dosing.
  • Easy and Accurate By Dr. P on 2/13/2015

    This kit is easy to use and accurate. I have been using it for several years and am very pleased with its performance.
  • Good By Kerry on 2/10/2015

    Easy to use. Read the instructions and there is a wonderful youtube video...
  • Facil Lectura By Hector on 12/29/2014

    Los colores son muy facil de leer mucho mejor que API definitivamente la unica razón por que le doy 4 estrellas es porque uno de los frascos se quebro de la punta cuando lo enrosque en la pipa no tengo idea porque pero son muy fragiles pero es muy buen kit. muy recomendable. :)
  • Excellent Test Kit! By Dustin on 11/24/2014

    Much more exact measurements than the API kits everyone starts with. I can't believe it took me 8 years to find this level of accuracy.
