I've only used this test kit twice and the print on the syringe is fading. Can't read any readings. It's designed to read your test results by hold it upside down and read what's on the syringe the print is backwards to get that reading so you can't just use another syringe. Not happy.

5.0 out of 5 stars Best test kits on the market.

Salifert had issues in the past, which they addressed. The Salifert tests are now top of the market for ease of use, accuracy, and speed. They also contain a vial of calibration fluid which will enable you to check your kit if you feel the need. As with all test kits, check the expiration date. Use this in combination with the magnesium and calcim test kits. If these three readings are held in recommended balance, the water chemistry will stay proper for marine fish and corals.

Alkalinity is one of (if not the most) important parameters to keep in check within a reef tank. Don't mess around with the lives of your animals, get a test kit you can rely on. I used to use the API test kits, but now will use Salifert exclusively. These kits are great, they're all really straightforward in operation and reading. From the moment you start testing, you can tell there is quality to this kit

Bought this in order to accurately measure CO2 in my 50l aquarium.
It's quite complicated to measure but the results are accurate.
HOWEVER...
The small pipette that is used to add the reagent has markings along its length and these are coming off after only a few uses!
I am contacting the supplier and will alter my review accordingly.
Update:
Contacted the supplier and got this rude reply:
Hi
I dont recomend or run down any aquatic products and I have been running My aquatic Shop and Famiyl business for 46 years. We are the oldest Family run Aquatics Business in the UK.
Its my job to give my Customers what they want and Salifert kits are amongst the things that they want so threats from you will not stop me.

PS. I note that you have not given me your order number so your threats are hidden behind annonimity.

The package was crushed and the tip was missing from the small sample syringe, bottle of reagent crushed don’t think it has leaked.
Must have been at the bottom of a lot of heavy stuff.

Was not happy with product. I love the Salifert for sure and will continue to use but this batch was bad and giving me very low readings on a tank that has a KH of around 10. I was getting readings of 7. However I have two other sources telling me the correct KH. Must have been sitting on the shelf for a while or just a bad batch.
