API 5-in-1 Test Strips for Freshwater and Saltwater Aquariums, 100-Count Box

For the 5in1, ignore any reviews that says they don't work. They work perfectly. I had poor water quality and the strips immediately detected high nitrate and nitrite levels. After days of water conditioning (interpet fast filter start and tetra easybalanxe) the nitrite and nitrates are both perfect now. I can visibly see improvements with my snails and shrimps, so I can definitely say they are accurate. Super easy to use. Dip and check in 30 sec.

We are new to tropical fish keeping and wanted to get these to help us keep a check on our water levels. They are great and easy to use, but it does not show you what the ideal levels are so we had to research this on online. A little chart or guide would be handy. Would buy again and came really quickly and in sensible packaging.

All good. I am not how sure how accurate it is but it's been doing the job. Good if you need something temporary. Delivered fast.

Massive value for money,as this is an essential thing with fish keeping il always buy them from here now the price for a 100 of them was brilliant x

Quick delivery.easy to compare to container for values against colour but no indication or paperwork to compare once you have the readings to show in safe parameters.

The readings are fairly accurate, I have compared the results against the API liquid tests, JBL ProScan strips andthe PH with a calibrated PH meter. Some readings are a little harder to read than others and always seems to end up between two shades/readings. Overall they are accurate and good for a quick spot check of your aquarium

Handy to keep by fish tank to check levels of Ph, etc in water

Great for a quick check. Not totally convinced of the accuracy,but seems pretty close.

Api some of the best products in the world always recommend them!

Bien qu''indiqué pour eau de mer, les résultats ne sont pas fiables. Déçue de mon achat vu le prix. Seules les valeurs nitrite et nitrate sont correctes. Mais il en va de même avec des tigettes meilleur marché.

It's definitely important to keep an eye on your fish's health by monitoring them closely, but it can be a little difficult to gauge the water quality just from their behavior alone. Often times when fish start acting strange, it can be too late. That's why these water test strips are so invaluable! You just stick them in the water, swish them twice, and then take them out with the water still on them. Then you can check your water quality by following the color guide on the bottle. The instructions are super easy to understand, and the test strips match the color swatches on the bottle without much deviation so it's easy to read your water conditions. The strips are plastic with little patches on them, so you don't have to worry about them disintegrating while you read them either. (They're durable. Are you happy Amazon suggestions? It just can't read between the lines...) One thing to note is that these strips don't test for ammonia levels in the water, which is a super important thing to monitor too. A little disappointing, but easily fixed by buying a separate ammonia test kit. They aren't quite as reliable as liquid tests, but overall a very useful and easy way to make sure your fish stay happy and healthy!

It is very convenient, fast and easy to read, the result is similar with their Master Test Kit. If your water has super high PH, you will need to buy the Master Test Kit.
