"Thanks Seachem."

The nitrate test is a little finicky as most users will agree. No issues so far, test strips work well. My tap water actually was really green and was a very close match to the 1. These are working very well for me. This is essential for an accurate reading. Best price, best quality, fair accuracy and better than most brands, etc. I will now test my water periodically to make sure everything is ok.

  • NilocG Aquatics Glass Co2 Drop Checker with 4dkh/PH Solution | Quickest, Most Accurate & Easiest to Use Glass Co2 Drop Checker with 4dKH/Ph Reagent Most Accurate Monitoring of Your Co2 Levels
  • WHY SHOULD YOU PURCHASE THIS DROP CHECKER AND INDICATOR SOLUTION: The biggest reason is that it comes with 4dKH fluid and ph reagent PRE-MIXED. If you aren’t using 4dkh fluid your reading is very unlikely to be accurate. Second this drop checker is very easy to use and fill. No need for syringes and other items, the indicator solution comes with a flip top bottle for extremely easy use.
  • IMPORTANT- MUST READ- It is very important to use 4dkh fluid and ph reagent in your Co2 drop checker. If your drop checker directs you to use tank water then it will not be accurate and you will not have a good idea of what the actual co2 levels are. If your co2 drop checker doesnt list 4dkh fluid then assume you dont have it. Its a must have for optimum accuracy!!!!!!!
  • Highest Quality Co2 Drop Checker With 4dKH/PH solution. Monitoring co2 levels in your planted aquarium is very important for the health of your plants and fish. This kit is complete with everything that you will need. It includes: High quality drop checker, suction cup, 60ml bottle of 4dkh/ph reagent solution.
  • EXTREMELY EASY TO USE CO2 DROP CHECKER- To use simply fill the drop checker half way with the Co2 Indicator Solution. Place suction cup on the drop checker and place in your planted tank. Wait 2 hours to read Co2 levels.
  • HOW TO READ CO2 DROP CHECKER- When your co2 is off the drop checker solution will be a deep blue color. After co2 has been on for around 2 hours you should notice the color change. Optimal co2 concentration will be at 30ppm which will be a green-light green color. If it remains blue your co2 is too low. If the color turns yellow then your levels are too high and may harm your fish. USE THE COLOR CHART ON THE SIDE OF THE CO2 INDICATOR SOLUTION or ON THE PRODUCT INSERT-

NilocG Aquatics Final Thoughts

"However, it is not."

I'm the test strip came in handy it saved all of my fish. Takes about 5 minutes to check everything. Very helpful for checking the water in our tank. Just dip the strip in the tank water for two seconds, then read right away. Dip it in the water horizontally and keep it horizontal and read it against bottle. This is a good kit so much more accurate and easy to figure out how to use it. Probably won't buy again because of the bleeding issues.

"Super easy to use."

Dip it in the water horizontally and keep it horizontal and read it against bottle. Overall, I am very happy with this kit. But after last night these are a must have for me. All bottles clearly labeled and tell you how many drops. I have a freshwater tank that includes some delicate invertebrates. These helped me check the levels and they were easy to use. A plus is that they don't bleed colors while testing.

PetSure! Final Thoughts

"Used the same kit before."

These have worked to keep my fish safe and healthy. To test it, I bought a 5 pack of 5 site test strips from Petco. It was also kinda hard to get exactly 5ml Into the tubes. If you're looking for a quick-hit on a range of water quality these are the answer. I found running all the tests took me around 10 minutes. I have a 55 gallon tank with a few large goldfish. I was having trouble keeping my fish tank water looking good.

"1 dKh difference."

My tap water actually was really green and was a very close match to the 1. The key is that you are looking for changes. Very good instructions and a comparison color chart. So off to buy some sponge filters I went! Here's Tetra's strips if you're curious. Tank lids, water additives and more have seen the same effect. Very helpful for checking the water in our tank.

"This is a good item."

The price is great for all these essential tests! If I had a complaint, I wish the color legend was printed on the bottle. But just for a quick check, its hard to beat these test strips. It you take it to a local fish store. The strips are packaged well so they stay fresh and ready to use. Very easy to use and very easy to read test strips. I wouldn't call this a master kit but a great start.

AlphaTRAK Final Thoughts

"25 from 0."

Dip it in the water horizontally and keep it horizontal and read it against bottle. I have not had any problem whatsoever. Also, I'd avoid Tetra's strips to be honest- the reviews speak for themselves. It looks to have the slightest green tinge but is not as green as the 0. The kH pad sometimes has the same problem as well. Nice that so many things are tested with one dip in the water. The nitrate test is a little finicky as most users will agree.

"Good value."

I cut each strip down the middle so that I have even more tests. I'm still not sure about the chlorine site. This test kit is easy to use and the results are easy to read. Some of the readings develop better than others. The stripa are easy to use, clear instructions and I gor results in seconds. It's difficult to tell if all the test sites on the strip are accurate. I have some pretty lousy water where I live.

It's quick and easy and can give you an alert if something may be going on. So I got these to try and I love them. Always nice to get something extra!

"Thanks Seachem."

It is easy to use and accurate enough. The API Test Strips are a good water monitoring system for small tanks. They quickly shipped me a new product. Their Whisper 1-5 filter cartridges have skyrocketed in price and become a scarcity. I wouldn't call this a master kit but a great start. I even got an extra 32 test strips as an added bonus. Definitely recommend this test strip for anyone who has a Betta fish as a pet.
