Must have test kit for all freshwater aquariums

I bought the API test kit after I lost almost my entire fish population to ammonia poisoning. This is a great all purpose testing kit for anyone who has a freshwater fish aquarium. I have used it several times and it's very easy to use.

This test kit was not complete, in that it was missing the reagent strips for the iron test. However, the rest of the kit worked well and the seller was very responsive. This water test kit comes complete with materials to test for bacteria, lead, pesticide, chlorine, copper, iron, nitrate, nitrite, alkalinity, pH, and hardness. I was most concerned about lead (looking at you, Flint, Michigan) so it was nice to have that quick response allaying my fears. Most of the tests are finished within just a few minutes.  The lead and pesticide strips take 10 minutes, and the bacteria vial must sit for 48 hours to give any present bacteria enough time to grow.

The instructions are straightforward and easy to read, with pertinent bits (like "DO NOT SET IN DIRECT SUNLIGHT" or "45 seconds") in bold print. It also comes with a booklet of more information, so if you do turn up with an abnormal result you've got a little more information at hand about what it means and what you should do next.

As long as you are willing to risk the iron test being absent (seems like several reviewers had the same issue), this is worth your money.

We bought this to "restart" out Sea Monkey aquarium after the previous ones had run their course.  Great kit gives you everything you need!

I don't test too often as my tank is pretty small (6 gallons), but this testing kit comes with all the basics in one nice package.

I used this test kit and also had a sample of water send to a lab for testing and the results were identical. Very pleased.

Testing the water in my salt water tank couldn't be any easier.  Quick accurate results.  Exactly the same results as LFS.

Worked great for my 50g mixed reef tank. I have a lot of corals, inverts, filter feeders such a sponges and feather dusters. I had an ich outbreak which I lost most of my fish in I lost 1x yellow tang, 1x blue hippo tang, 1xlion fish 2x clown fish and 1 green chromis I did setup an established hospital tank which was a total fail my fish got even more stressed during the whole moving tank. So I gave my tank a few weeks without any fish so 3 days ago I purchased a new pair of wild caugh tomatoe clown fish from my lfs within a few hrs of being in my tank I noticed they already had white spots on them I was so angry so I saw this product and figure I'd give it a try I had no other option so I did and I'm so glad I did this I should of done this from the very beginning I might still have most of my fish with me. DONT LISTEN TO THE PEOPLE THAT WILL TELL YOU THAT THIS DOESN'T WORK Because I have a fully stock reef tank and did this the job 100% you're supposed to dose 5ml per 10 us gallons I have a 50g with a 20g sump so I dose 5ml 7x also don't be afraid to dose mutiple times a day I did it twice the first day and then 3x the 2 days after that. I used the product for a whole week, IMPORTANT remove your carbon, media, any sort of filtration you have in your system as this will remove the medication from the water and we don't want that also TURN OFF your skimmer if you have one, micron socks are Okay to leave just shut off any media reactors or remove media bags whatever it is you might have. I hope this review makes other reefers feel safe using this !

My only problem is that I never purchased this a lot earlier.  I was having severe problems with the nitrate levels in my tank.  No matter what i did, I couldn't get it at a comfortable level.  I added this to the tank and it was like saving grace to the fish.  I bought another bottle and would occassionally a few mLs when I change the tank's water.  Tetra is the best brand for all your aquarium needs.  I recommend them 200%!

Works as advertised, results within 3 minutes. Color chart is easy to distinguish with test tube.  Local fish stores use this brand and also seems to be a popular choice among hobbyist for liquid testing of Nitrites and Nitrates. Probably the most accurate brand for liquid testing. Although reality is for phosphates it should be considered to get a digital read out device like a hanna checker.

This is an excellent kit.  Titration type testing is definitely more accurate than strips, cheaper and I believe more trustworthy than photometer type testing. Taylor does it right and they have been in the business a long time.  The "Watergram" water balance calculator (included) is a great little tool for helping decide where to make adjustments toward sustainable balanced water.  Also included was a little (waterproof) book "Pool and Spa Water Chemistry".  It is an EXCELLENT publication!  Full of good, time tested information and well worth taking the time to read.  We have a new spa and our well water is a little bit of a bother to get balanced but I needed to get it right,  We have a lot of money invested so I want to take care of our spa and above all we want sanitary water.  Titration testing (drops) is no big deal - that is if you can count :).  It literally takes minutes and I have the most confidence I can get at home with this type of testing and a quality product.  I have noticed that most quality spa/pool supply stores also have Taylor reagents on the shelf which speaks for itself.  I did make and addition to my kit by cutting a good quality plastic drinking straw in half and I stir vs. swirl when adding drops. Speeds up the process and gives a good and thorough mixing.  I rinse every component well after testing.  The kit is quality - slots for all components - and a great storage box.  A good investment for your pool or spa.

Works exactly as it advertises. It's another great meter to have for testing the aquariums. I still use a liquid test kit, but so far this is a lot quicker, and is a great way to schedule water changes.

I love this product. It helps me remove Chlorine and other contaminants from my tap water. I live in NYC and our water is already soft but we have old rusty pipes and this allows me to take it the extra mile and make it fully safe.

I recommend this for Freshwater fish, Saltwater aquariums need a RO/DI system

Throw those useless filters away and get a couple bags of this. My tank was shot when someone told me about purigen. I ordered 4 bags, two for the filter and 2 for standby ( you never have to buy any more after that ). I fought for almost a month doing the water changes and everything else you're supposed to do but after I put the purigen in my filter it took only 3 days and my tank was clear, ammonia free, nitrite and nitrates are at perfect levels. This stuff saved my beautiful tank. I will NEVER use anything other than Purigen in my tanks.

We purchased this test kit and it contains the basic tests for what was needed for our freshwater aquariums.  We test 5 tanks regularly at home, when we used to take samples all the way to the fish store.  The instructions are very easy and we get results within minutes.

The peace of mind that your pets are ok is worth buying quality and reliable brand like NutraFin.

This was suggested to me by several fellow fishkeepers over at aquaticcommunity.com . It works great, and is a great help as I get my tank set up & cycled. Now I can test the tank water daily, and do partial water changes as needed.
You can test your water parameters many times with this kit, so the approx. $25 I spent on this was a really good deal.
