Full Details

The pH value or acid value indicates how acidic or alkaline water is. It is a measure of the concentration of the acidic or alkaline components in a hydrous solution. Pure water will react neutral and has a pH-value of 7.00 . If the acidic components are predominant, the pH value will drop below 7.00. If the basic components are predominant, the pH-value will rise about 7.00. The SaltWater aquarium pH-value is considered between 8.1 and 8.4 pH which is the value found in natural seawater. Many organisms will react with high sensitivity to very small variations of the pH-value. An overly drop or rise should be avoided absolutely. Most of the organisms reacts sensitively (or die) on a pH-level, which is constantly far away from the requested value as well as on gravid modifications. Therefore, a regular check on the pH-level is elementary necessary to note and to avoid any negative development.

Keeping proper water quality in our aquarium is a fundamental step toward a healthy tank. To properly monitor your water quality you need an accurate and reliable set of test kits.

All Elos test kits include:

  • Calibrated lab droppers: the accuracy of a titrimetric test kit is, in fact, strictly related to the precision of the drop size.

  • RealColor technology: the precision of a colorimetric test kit is strictly related to the precision of the color chart. In these test we use an accurate system to calibrate the color chart compared to the reagents.

  • The validation of each batch of reagents through the use of NIST (National Institute of Standard and Technology) certified samples.

  • The strict control of the supply and storage chain: test kit reagents are very delicate, their accuracy is significantly influenced by storage. For this reason we keep our stock strictly under control and we suggest, to all our retailers, to do the same.

  • The use of Lab Quality reagents: to grant a constant, precise result like only professional products may permit. Not only are the reagents included in all Elos test kits precise but we use non-toxic reagents whenever possible.


  • High precision: thanks to the use of calibrated dropper

  • NIST validation: each batch is validated using NIST (National Institute of Standard and Technology) samples

  • High number of test per kit: up to 40 test (with a standard level of 10 dKH)

  • "Safe reagents": reagents and testing procedures are based on Low Risk Reagents. None of our test kit are based on Toxic Reagents

  • Great product By Jeremy B on 6/25/2016

    So I had been using a API PH test kit and was like someone else mentioned having a hard time really deciphering between numbers like 8.0, 8.1 and so on. This test kit gives you I would say a 85-90% verification when you look at it. Meaning depending on what lighting you are under and how exactly you are looking at it. I recommend trying to stand beside a door or window and use natural sunlight...seems to work better. As for the percentages what I meant was when I look at it I'm like "Yeah that looks like 8.1...might be 8.2 but I'm pretty sure its 8.1. I'm also probably a tad color blind people because my gf makes it out easy when I show her with no questions asked. Its definitely better than the API test kits. Its also an easy to use kit in general. I wish the doper bottle was a little better...it leaks out the fluid pretty easy on initial flip upside down and you may add an extra drop if your not careful. I have not tried the Saferit PH kit...ALL my other kits are saferit but if I had to guess I think this one for some reason would be better...for some reason it seems like the manufacturers that charge more for this probably use a solution that cost more to make which makes it easier to read...this is all speculation here clearly. I feel that for me the few extra bucks on this particular kit is the way to go. Buy it.
  • bad By casey on 12/8/2014

    I have lab grade probe from you guys calibrated ten times and check with elos gives me false reading !!!!
  • Avoid a trip to ER By George on 3/11/2014

    Avoid a trip to ER i bought the elos ph calcium and nitrate test kits went to do ph test following instructions went to place cap on tube and it was tight i tried to push a little bit but then glass broke in my hand. the two other test kits are the same cap is to big for tube also tube feels really thin. i was so excited to use the test kits now a have a useless kits and a trip to the ER to Get the glass out of my hand
  • Very good color contrast By Chris on 2/13/2014

    I've used the salifert ph kit for over a decade. The problem with it for me is the color contrasts aren't enough. Due to being color blind I have a difficult time telling the difference of values. The Elos kit provides a better contrast for me.
  • Best PH test Kit By Leo on 9/19/2013

    This Test kit is easier to read then most brands out there highly recommend using Elos.
  • Awsome test kit! By Toby on 2/15/2013

    These are very accurate and the color chart is easy to differentiate.
  • my favorite test kit By John on 1/27/2013

    i could not read the colors to charts on red sea ph this elos is great even with older eyes color/charts is very easy very highly recommend this
  • Very Accurate By Brant on 6/17/2011

    I have used API in the past but these tests are so much easier to read.
  • Great test kits! By Christopher Kosak on 10/7/2010

    I only use ELOS kits after switching from the API kits. I believe ELOS has the best test kits and they are top notch quality. The PH kit is very easy to use and im sure you will not have a hard time conducting this test kit.
