1. Salifert Nitrate (No3) Test Kit

All Seas Marine SI021 First Impressions

"25 from 0."

The API Test Strips are a good water monitoring system for small tanks. It is easy to use and accurate enough. 6 and run a high pH you will see it could actually be 7. So I got these to try and I love them. This is essential for an accurate reading. They showed the same results as these for the sites they had in common. I tested the water and the nitrates and the ph were pretty high still.

All Seas Marine SI021 Final Thoughts

"Great value, Speedy ship!"

The key is that you are looking for changes. Tetra has always done that and I will continue to use their products. I found running all the tests took me around 10 minutes. First few strips I used gave an accurate ready. The stripa are easy to use, clear instructions and I gor results in seconds. Not sure if the reading is 0 or more likely something between 0-. In my opinion they arent quite as accurate as master test kits either.

"So they're measuring!"

If this review was helpful, please click the helpful button! So this thing worked very well and gave a reading that made perfect sense. If I had a complaint, I wish the color legend was printed on the bottle. Not sure if the reading is 0 or more likely something between 0-. Wasn't labeled that way in the descriptor. Strips are accurate as far as I can tell. They test pretty accurate when run against my chemical tests.

Red Sea Fish pHarm FBA_63321465 Final Thoughts

"Worked great."

It shows it could be between 1-20 but the liquid shows 0. It looks to have the slightest green tinge but is not as green as the 0. I set up a bunch of 20 gallon tanks for fry and stuff. If I had a complaint, I wish the color legend was printed on the bottle. About my pic color difference of the water and the chart and about the bad reviews. Overall good value for a small hobbyist aquarium owner. This is no different so I wouldn't knock this product for that.

"It's that easy."

The nitrate test is a little finicky as most users will agree. I wouldn't call this a master kit but a great start. I even got an extra 32 test strips as an added bonus. Before, I brought water into a pet store, but kept seeing no signs of improvement. The key is that you are looking for changes. Then put the cap on the test vial and invert it several times. The strips are able to monitor pH, nitrate, nitrite, water hardness.

"To support my claim."

This test kit is easy to use and the results are easy to read. If you're out for speed, but with less accuracy get the dip tests. 32 seconds and I have a reading and I'm on my way with no mess. My results are never all over the place like other reviewers. Probably won't buy again because of the bleeding issues. I don't know so much about how precise these are. I would not use it solely for checking nitrate and nitrites.

Having the key on the bottle is very helpful, it won't get lost. 32 seconds and I have a reading and I'm on my way with no mess. Just dip the strip in the tank water for two seconds, then read right away. Nice to have in hand when you own an aquarium. The strips are packaged well so they stay fresh and ready to use.

Every test I do takes just a few drops. I even got an extra 32 test strips as an added bonus. If you're out for speed, but with less accuracy get the dip tests. If you're looking for a quick-hit on a range of water quality these are the answer. Will definitely buy again, if we ever run out! Very good instructions and a comparison color chart.

"Great test kit."

It does take some time though to actually get it done. Well I found out why they were gulping so bad. They're super easy to read and seem to be pretty accurate. Here's Tetra's strips if you're curious. 6 showing the test strip as an accurate reading. It's difficult to tell if all the test sites on the strip are accurate. I set up a bunch of 20 gallon tanks for fry and stuff.

6. Salifert Calcium (CA) Aquarium Water Test KIT - Fresh & Marine Fish Tanks

Salifert First Impressions

"These strips are great."

Accurate results and much much cheaper than buying from a pet chain. But it is accurate and convenient as is. Here's Tetra's strips if you're curious. This test kit is easy to use and the results are easy to read. Very good instructions and a comparison color chart. I have some pretty lousy water where I live. My results are never all over the place like other reviewers.

  • Salifert Calcium (CA) Aquarium Water Test KIT - Fresh & Marine Fish Tanks
  • Item description The color change is sharp and facilitates the detection of small but highly significant fluctuations in the calcium concentration. Salifert's Coral Calcium additive is manufactured using a very special procedure.
  • NSW contains 400 – 450 mg/L calcium. Which is also the value we should strive for. For a stable aquarium environment the fluctuation in calcium content should preferably not more than approx. 15 mg/L. This automatically means that the calcium test should be able to monitor comparable fluctuations.

"Easy to read."

No one brand is going to guarantee against this. Strips were always stored in a sealed dry place. I will now test my water periodically to make sure everything is ok. So did another water change today and now I have happy fish. Very helpful for checking the water in our tank. These strips are not to be trusted as a primary testing method for aquariums. Nice that so many things are tested with one dip in the water.

But it turns out that is not the case. Every test I do takes just a few drops. I was having trouble keeping my fish tank water looking good. In my opinion they arent quite as accurate as master test kits either. I take every precaution about the chlorine, and trust the strips for everything else. If you're out for speed, but with less accuracy get the dip tests. Having the key on the bottle is very helpful, it won't get lost.

32 seconds and I have a reading and I'm on my way with no mess. Not really sure if there is a way to fix that though. I take every precaution about the chlorine, and trust the strips for everything else. So off to buy some sponge filters I went! A brand new aquarium will experience what is called a cycle. But after last night these are a must have for me. If your lighting isn't right the colors will be very off.
