Alkalinity Calcium Magnesium Combo Test Kit

Very good. more accurate than other brands

Works very well. Accurate readings. Packaging could have been better. Boxes were placed in clear plastic bag and taped. Some boxes were crushed. No damage to the test tubes thankfully. Would have been better had they been shipped in a box.

Nothing beats salifert been using it for as long as I've been in the hobby.

These are by far the best test kits. They are extremely accurate and all the syringes are accurate as well. Only reason I give it 4 stars is because there’s a step in which you draw up the reagent and there’s always an air bubble that changes in size. The instructions say that the air bubble is normal, but the size of it fluctuates so it doesn’t make sense. Some YouTubers say it has to be a certain size but it’s difficult to control the size of an air bubble.

100% Recomendado.

3 salifert test kits for one low price..what more can one ask for? Came well packed, complete, and no where near the expiration date. This is a good deal.

Reef keepers may balk at this negative review as user error, and I guess it partly is, however nothing on the box or in the main product description lists this test as saltwater only. I keep mainly freshwater planted aquariums and we also closely monitor calcium and magnesium in the water since we’re constantly dosing fertilizer. Most test kits in the market are for both saltwater and freshwater so I assumed this kit was the same however the issue is that there is much less calcium and magnesium in freshwater vs saltwater and the testing range of this kit can only detect high levels of calcium (~350ppm and above) and magnesium (unsure of min). What’s worse is Amazon doesn’t accept returns for this item at all so I’m left with $50 down the drain. As far as the kit itself, as a first time user I will say that it was confusing for me. Before realizing this kit doesn’t work for freshwater I went through multiple attempts and the instructions weren’t great. As an example for the calcium test you have to draw 1ml of testing liquid however the shape of the syringe provided creates a large air bubble so you are really only able to draw around .8ml of liquid. The instruction then tells you NOT to try and remove the air bubble but then it says to gradually deposit the “1ml” of liquid which you never fully obtained in the first place. I think the issue is a translation problem but nevertheless it’s confusing and I saw multiple posts online with people confused about the process. Overall though I know Salifert is general considered to be a good brand, just apparently with bad translation.

Had no problem using the tests they make it easy to understand! Will continue to use.
