Aquarium Equip PTM691I506 First Impressions

"This part is very easy."

I take every precaution about the chlorine, and trust the strips for everything else. Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. No one brand is going to guarantee against this. I find that the accuracy is wrong in the sense it's better than it reads. But just for a quick check, its hard to beat these test strips. Not really sure if there is a way to fix that though. 6 and run a high pH you will see it could actually be 7.

Aquarium Equip PTM691I506 Final Thoughts

"Super easy to use."

Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. I have a freshwater tank that includes some delicate invertebrates. This is no different so I wouldn't knock this product for that. This is not the right way to use this test, as it took me awhile to realize this. Will definitely buy again, if we ever run out! The stripa are easy to use, clear instructions and I gor results in seconds. Here's Tetra's strips if you're curious.

"Exactly what I needed."

So off to buy some sponge filters I went! I find that the accuracy is wrong in the sense it's better than it reads. These strips are not to be trusted as a primary testing method for aquariums. It's really accurate and makes me feel like I'm a scientist while doing it. It looks to have the slightest green tinge but is not as green as the 0. It does'not' have the same accuracy but it’s very close. It looks to have the slightest green tinge but is not as green as the 0.

"He perked right up."

These have worked to keep my fish safe and healthy. Having the key on the bottle is very helpful, it won't get lost. So off to buy some sponge filters I went! The rest of the test in the kit are much easier to use. The test strips work as advertised. If you're out for speed, but with less accuracy get the dip tests. My water was good to go and soon after I for fish that are doing well!

"This part is very easy."

I find that the accuracy is wrong in the sense it's better than it reads. The key is that you are looking for changes. They show results, what is safe& not safe and what to do if not safe. My 12 yrs old son wanted a fish tank so we got him 2. 6 showing the test strip as an accurate reading. I have not had any problem whatsoever. If you keep freshwater fish, you will need this test kit.

Sera 4410 Final Thoughts

"These strips are great."

Wasn't labeled that way in the descriptor. Strips were always stored in a sealed dry place. As you can see in comparison the only difference was the Nitrate. Not really sure if there is a way to fix that though. I set up a bunch of 20 gallon tanks for fry and stuff. Not sure if the reading is 0 or more likely something between 0-. 6 and run a high pH you will see it could actually be 7.

"He perked right up."

Tetra has always done that and I will continue to use their products. So did another water change today and now I have happy fish. Every test I do takes just a few drops. Some of the readings develop better than others. I mean some people would never do a water test at all. So did another water change today and now I have happy fish.

"This part is very easy."

I tested the water and the nitrates and the ph were pretty high still. Just be careful, after all these are chemicals. If you're out for speed, but with less accuracy get the dip tests. If you keep freshwater fish, you will need this test kit. If your lighting isn't right the colors will be very off. If I had a complaint, I wish the color legend was printed on the bottle. Probably won't buy again because of the bleeding issues.

5. WAGA Glass Drop Checker Aquarium Fish Tank Co2 Concentration with Test Solution

WAGA First Impressions

"However, it is not."

It does not test ammonia but that's clear in the description and bottle. So off to buy some sponge filters I went! This is no different so I wouldn't knock this product for that. Some of the readings develop better than others. But after last night these are a must have for me. I tested the water and the nitrates and the ph were pretty high still. Nice that so many things are tested with one dip in the water.

  • WAGA Glass Drop Checker Aquarium Fish Tank Co2 Concentration with Test Solution
  • This glass CO2 drip checker is used to monitor the CO2 dose in the aquarium.
  • Simply fill the CO2 indicator solution, and the solution will change color to indicate the CO2 content in the aquarium water.
  • The CO2 inspection glass and suction cup are included in the package.
  • How to set up a CO2 indicator solution for a CO2 checker: Add 4 dkH reference solution to your droplet checker. In addition, you need to add 3 drops of pH indicator. (It is bromothymol blue).
  • What is 4 dkH: 4dkh water is used in the droplet checker because it has a reliable buffer level, which happens to make the color change of the indicator fall on about 30 ppm CO2. The hardness of the water in the storage tank does not matter. In theory, it will not come into contact with the contents of the droplet checker and therefore will change the color. Use liquids of different intensities to move the indicator's changing points to adapt to different CO2 levels.

WAGA Final Thoughts

"That is time consuming."

Overall, I am very happy with this kit. I started wearing gloves when I use the kit. Very easy to use and very easy to read test strips. A brand new aquarium will experience what is called a cycle. I find that the accuracy is wrong in the sense it's better than it reads. I even got an extra 32 test strips as an added bonus. If you keep freshwater fish, you will need this test kit.

These have worked to keep my fish safe and healthy. Having the key on the bottle is very helpful, it won't get lost. This test kit is easy to use and the results are easy to read.

Red Sea 306026 Final Thoughts

"Gives me peace of mind."

The strips are able to monitor pH, nitrate, nitrite, water hardness. But if it's wrong at least I was proactive about it. Always nice to get something extra! Before, I brought water into a pet store, but kept seeing no signs of improvement. I respect a company that backs their product. The strips are packaged well so they stay fresh and ready to use. If I had a complaint, I wish the color legend was printed on the bottle.

"These strips are great."

But it turns out that is not the case. I found running all the tests took me around 10 minutes. Best price, best quality, fair accuracy and better than most brands, etc. 32 seconds and I have a reading and I'm on my way with no mess. It's really accurate and makes me feel like I'm a scientist while doing it. I wouldn't call this a master kit but a great start. Very good instructions and a comparison color chart.

"3 and not 0."

These helped me check the levels and they were easy to use. It you take it to a local fish store. They quickly shipped me a new product. But after last night these are a must have for me. A plus is that they don't bleed colors while testing. I'm the test strip came in handy it saved all of my fish. I find that the accuracy is wrong in the sense it's better than it reads.

"Worked great."

Dip it in the water horizontally and keep it horizontal and read it against bottle. I tested the water and the nitrates and the ph were pretty high still. Before, I brought water into a pet store, but kept seeing no signs of improvement. This is not the right way to use this test, as it took me awhile to realize this. So this thing worked very well and gave a reading that made perfect sense. I get a consistent reading every time, retests included. Definitely recommend this test strip for anyone who has a Betta fish as a pet.

"I kid you not."

32 seconds and I have a reading and I'm on my way with no mess. Quantity of strips seems very good. If you keep freshwater fish, you will need this test kit. I have not found that to be true for myself. I'm still not sure about the chlorine site. A plus is that they don't bleed colors while testing. I tested the water and the nitrates and the ph were pretty high still.

"Two packages were inside."

Not sure if the reading is 0 or more likely something between 0-. I was having trouble keeping my fish tank water looking good. The caps do leak a tiny bit on the tubes. But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip. The API Test Strips are a good water monitoring system for small tanks. I started wearing gloves when I use the kit. It is one small part of the overall aquarium ownership experience.

"I don't know."

This kit is extremely accurate and very well designed for convenient use and storage. It is easy to use and accurate enough. Then replace the caps of the bottle and test vial. No issues so far, test strips work well. Just dip the strip in the tank water for two seconds, then read right away. But it is accurate and convenient as is. Not really sure if there is a way to fix that though.
