Fluval A7551 First Impressions

"Bought the 100 Count."

And if it was, please click on the helpful button below. Very good instructions and a comparison color chart. I take every precaution about the chlorine, and trust the strips for everything else. They show results, what is safe& not safe and what to do if not safe. I wish there were a simpler accurate test for it. I don't know so much about how precise these are.

Fluval A7551 Final Thoughts

"Maybe I have bad bottle."

The kH pad sometimes has the same problem as well. They test pretty accurate when run against my chemical tests. They show results, what is safe& not safe and what to do if not safe. This kit is extremely accurate and very well designed for convenient use and storage. Wasn't labeled that way in the descriptor. This is a good kit so much more accurate and easy to figure out how to use it. Also, I'd avoid Tetra's strips to be honest- the reviews speak for themselves.

API 33G First Impressions

"Maybe I have bad bottle."

If you're looking for a quick-hit on a range of water quality these are the answer. If this review was helpful, please click the helpful button! Well I found out why they were gulping so bad. While using these weirder chemicals, it worries me a little bit. You mostly find them using API also. To test it, I bought a 5 pack of 5 site test strips from Petco. But if it's wrong at least I was proactive about it.

API 33G Final Thoughts

"I disagree."

Having the key on the bottle is very helpful, it won't get lost. If you want accurate pH get the API liquid test that includes pH and high pH. This test kit is easy to use and the results are easy to read. I've already lost one test tube cap, most likely due to my cats playing with them. If this review was helpful, please click the helpful button! Besides these few flaws I have to say it's a great starter kit. This spreads out the 6 month expiration date after opening.

Sera 4945 Final Thoughts

"Fast result."

Dip it in the water horizontally and keep it horizontal and read it against bottle. I started wearing gloves when I use the kit. Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. This is a good kit so much more accurate and easy to figure out how to use it. Not sure if the reading is 0 or more likely something between 0-. But just for a quick check, its hard to beat these test strips. 32 seconds and I have a reading and I'm on my way with no mess.

Red Sea 306029 First Impressions

"So they're measuring!"

It does not test ammonia but that's clear in the description and bottle. This is not the right way to use this test, as it took me awhile to realize this. Tetra has always done that and I will continue to use their products. All bottles clearly labeled and tell you how many drops. My 12 yrs old son wanted a fish tank so we got him 2. They quickly shipped me a new product. Strips are accurate as far as I can tell.

Red Sea 306029 Final Thoughts

"This part is very easy."

They showed the same results as these for the sites they had in common. I would not use it solely for checking nitrate and nitrites. I respect a company that backs their product. A brand new aquarium will experience what is called a cycle. I've already lost one test tube cap, most likely due to my cats playing with them. These are working very well for me. Always nice to get something extra!

"Easy to use."

So this thing worked very well and gave a reading that made perfect sense. I have some pretty lousy water where I live. I would not use it solely for checking nitrate and nitrites. 32 seconds and I have a reading and I'm on my way with no mess. This spreads out the 6 month expiration date after opening. About my pic color difference of the water and the chart and about the bad reviews. If you keep freshwater fish, you will need this test kit.

"1 dKh difference."

I wouldn't call this a master kit but a great start. This test kit is easy to use and the results are easy to read. So off to buy some sponge filters I went! 6 showing the test strip as an accurate reading. Easy to use, a good quantity and quality for the price. It looks to have the slightest green tinge but is not as green as the 0. I don't know so much about how precise these are.

Salifert AMPT First Impressions

"Thanks Seachem."

It was also kinda hard to get exactly 5ml Into the tubes. I have not found that to be true for myself. The caps do leak a tiny bit on the tubes. They test pretty accurate when run against my chemical tests. I started wearing gloves when I use the kit. I even got an extra 32 test strips as an added bonus. Nice to have in hand when you own an aquarium.

"00 becomes 40."

It does take some time though to actually get it done. Comes with a lot of test strips, that are extremely easy to use and read. I set up a bunch of 20 gallon tanks for fry and stuff. This is no different so I wouldn't knock this product for that. First few strips I used gave an accurate ready. This is no different so I wouldn't knock this product for that.

"Simple and easy to use."

If your lighting isn't right the colors will be very off. As you can see in comparison the only difference was the Nitrate. If your lighting isn't right the colors will be very off. Some of the readings develop better than others. But it is accurate and convenient as is. In my opinion they arent quite as accurate as master test kits either. Best price, best quality, fair accuracy and better than most brands, etc.

A plus is that they don't bleed colors while testing. Just dip the strip in the tank water for two seconds, then read right away. If you want accurate pH get the API liquid test that includes pH and high pH. Here's Tetra's strips if you're curious. I respect a company that backs their product. It shows it could be between 1-20 but the liquid shows 0. As you can see in comparison the only difference was the Nitrate.

I have a 55 gallon tank with a few large goldfish. Not really sure if there is a way to fix that though. They quickly shipped me a new product. 6 showing the test strip as an accurate reading.
