API 5-IN-1 TEST STRIPS Freshwater and Saltwater Aquarium Test Strips 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.

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

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

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.

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

Judgement withheld as not decided on their accuracy....

Easy product to use and accurate.

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.
