IOAOI Aquarium Test Strips for Freshwater and Saltwater, 5 Pcs of Ammonia Test Strips and 100 Pcs of 7 in 1 Test Strips, pH, Alkalinity, Nitrite, Nitrate, Chlorine, Carbonate, Hardness

I own and operate a local youth facility. We have many reef tanks located throughout the facility. We ordered these test strips for daily testing and because we have purchased previous IOAOI products in the past and every item has been great thus far.I test bi-weekly with Hanna test kids and monthly with Salifert as a secondary to ensure consistent results. I purchased these test strips for daily use to monitor each of the tanks.Packaging - The packaging is standard for this type of product. The contents were packed neatly in the box and were undamaged.Contents - Contents of the package included a plastic bottle with screw on lid which houses the 7 in 1 test strips, a resealable package that contains the Ammonia test strips, a 5ml dropper bottle of Ammonia Nitrogen Activator, and a small 10ml test tube.Performance - The test strips have this far been accurate when compared to my other testing kits. These test strips have been great for daily testing to ensure that there are no major swings in water quality. I love ability to test daily with accurate results in just a matter of seconds.These test strips have been a great addition to my reef maintenance schedule! I am definitely a fan of IOAOI products! I couldn't be happier! I highly recommend!

I used these setting up a new saltwater tank with real live rock to help monitor the cycling of the tank. The ammonia was a waste of time, just get one of those Seachem ammonia alerts. These strips never showed a ammonia reading when obviously there was ammonia in the tank. If I have to use a dropper, like in the ammonia strips, might as well get another test kit for testing ammonia or just use a ammonia badge. I was pleased to see the nitrite & nitrates color up to indicate the cycle was going on & finishing up. They stayed white for several days then finally got a clear pink color on day 4. The Nitrate block will match other test kits. The nitrites went back to white a few days later & I was seeing nitrates rise along with another test kit. So it can definitely be trusted for nitrates. I'll continue to use them to quickly spot check, very useful for ph & nitrate. The other parameters need specific saltwater tables as they do not make sense to me.

I use Hanna and Salifert tests for most of my reef testing but it gets expensive and takes time. These test strips have somewhat wide ranges - as do all test strips - but it's a great way to make sure I'm close between tests. I like them and if you're not "chasing the numbers" they're very helpful! I also checked them against my Hanna checkers and found them to be accurate.

I use these test strips on a regular basis. They really have an accurate reading and highly recommend them.

It does what it says.

I like that they're not too expensive and there's a whole bunch of them and they should last you a long time to test your water

I get that test strips are not intended to be super accurate. The tests are mostly inaccurate to a degree that it makes using these not worth the 30 seconds it takes to use them. Alk tests so low it didn't even worry me, I use rc salt and with weekly wc and testing I know it's not that low. Ph is close so thats all I use them for. I also use Salifert, Hannah, and yes even api tests, those are all with in a slight margin of error with each other.

This won't replace more in depth checks, but it's great for a quick overview of your tank. The ranges line up with what I'm seeing from Hanna and Red Sea tests.I'd like to see saltwater and freshwater as different kits since a couple of these measurements don't matter in a reef tank.

Only wish there were more Ammonia test strips included. 5 is not enough compared to the 100 Nitrate/Nitrite tester strips included. But great deal for the Nitrate/Nitrite test strips! Work as expected, easy to use!

The ammonia test did not work. Lost a fish. Sad. The other test was not indicating there was a problem. I had my water tested at the pet store and yes ammonia and all other numbers were off.
