Tetra EasyStrips 6-In-1 aquarium Test Strips, Water Testing, Model:19543

Best test strips I've ever used, not as accurate as a liquid test, but good enough to get an idea of water quality, I have multiple aquariums and liquid test could take me a day to complete, with these its about an hour and if anything looks high or low then do a full liquid test.. saves time and money. the phone app is easy to use.. only downside is the 100 packs are only available outside UK. only 10s and 25s in UK but mine came from USA quicker than expected, so really no downsides.

Perfect

Fast postage, easy to use, takes 30 seconds, for hobby purposes it seems accurate enough and to that degree, I can tell the difference between the different shades of colours. I can confirm it gives different readings for tap, reverse osmosis, fresh, salt, my home tanks and store water. Apparently the individual test are more accurate, but take a lot longer to use (i.e. 3 mins for 6 different tests). Happy with purchase (especially as it was discounted when I purchased).

As anyone who has fish knows, water quality is essential for their survival in either a tank or a pond. Rather than using several testing mediums to test the quality of the water (one for each of the nitrates, nitrites, water hardness, PH, etc), I find it very convenient to test all the key elements at once with one little strip. The strips are very easy to use. All one has to do is to soak it in the water for one second and it provides all the readings 30 seconds later.

I bought these as a quick test. They seem to be very accurate for nitrates/nitrites and Ph. I also have the old fashion test kits. They seem to match up. Except, for GH and KH. I always get zero readings from the strips, but not from the old fashioned liquid test.
