Ailinda First Impressions

"Great strips."

I was having trouble keeping my fish tank water looking good. If you're looking for a quick-hit on a range of water quality these are the answer. Accurate results and much much cheaper than buying from a pet chain. These strips work very well and I have had consistent results with them. The nitrate test is a little finicky as most users will agree. 32 seconds and I have a reading and I'm on my way with no mess. 32 seconds and I have a reading and I'm on my way with no mess.

Ailinda Final Thoughts

"Exactly as pictured."

I will now test my water periodically to make sure everything is ok. It does not test ammonia but that's clear in the description and bottle. I set up a bunch of 20 gallon tanks for fry and stuff. These strips are not to be trusted as a primary testing method for aquariums. I have not had any problem whatsoever. The key is that you are looking for changes. They quickly shipped me a new product.

"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.

"Just sayin'."

But it is accurate and convenient as is. My 12 yrs old son wanted a fish tank so we got him 2. Nice to have in hand when you own an aquarium.

I'm the test strip came in handy it saved all of my fish. The rest of the test in the kit are much easier to use.

Tetra Pond 19542 Final Thoughts

"Was good for 3 years."

Price is good for the quantity and functionality of the tester strips. I have not found that to be true for myself. My tap water actually was really green and was a very close match to the 1. They test pretty accurate when run against my chemical tests. But if it's wrong at least I was proactive about it. If I had a complaint, I wish the color legend was printed on the bottle. Price is good for the quantity and functionality of the tester strips.

"However, it is not."

This is a kit to test for my aquarium water quality. Very helpful for checking the water in our tank. Nice to have in hand when you own an aquarium. A brand new aquarium will experience what is called a cycle. The strips are packaged well so they stay fresh and ready to use. I have some pretty lousy water where I live.

Checker Final Thoughts

"Great test kit."

Dip it in the water horizontally and keep it horizontal and read it against bottle. But it is accurate and convenient as is. A brand new aquarium will experience what is called a cycle. Strips are accurate as far as I can tell. And if it was, please click on the helpful button below. But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip. It's difficult to tell if all the test sites on the strip are accurate.

Sera 4310 First Impressions

"I love this test kit."

Probably won't buy again because of the bleeding issues. These helped me check the levels and they were easy to use. It does not test ammonia but that's clear in the description and bottle. I even got an extra 32 test strips as an added bonus. Nice that so many things are tested with one dip in the water. Nice to have in hand when you own an aquarium. So did another water change today and now I have happy fish.

Sera 4310 Final Thoughts

"These are just easier."

If you're out for speed, but with less accuracy get the dip tests. I have not had any problem whatsoever. This is essential for an accurate reading. I mean some people would never do a water test at all. 6 and run a high pH you will see it could actually be 7. It looks to have the slightest green tinge but is not as green as the 0. So I got these to try and I love them.

6. Seachem Purigen Organic Filtration Resin

User Ratings: 82 3

Seachem 116016506 First Impressions

"My favorite brand!"

It's quick and easy and can give you an alert if something may be going on. I've already lost one test tube cap, most likely due to my cats playing with them. I'm still not sure about the chlorine site. I set up a bunch of 20 gallon tanks for fry and stuff. It shows it could be between 1-20 but the liquid shows 0. I was having trouble keeping my fish tank water looking good. Comes with a lot of test strips, that are extremely easy to use and read.

  • Seachem Purigen Organic Filtration Resin
  • FILTRATION: Purigen ranges in color from almost white (cream) to light yellow. Seachem Purigen is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water.
  • SELECTIVITY: Seachem Purigen is an organic filtration resin that works hard to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making your water crystal clear.
  • CAPACITY: Being both spherical and macroreticular, Seachem Purigen has microscopic pores that increase its usable surface area to many times that of a purely spherical resin.
  • REGENERATION: Once Seachem’s Purigen is exhausted, it can be regenerated with a solution of bleach and water. The bleach will literally “burn off” the organics that have been removed from the tank.
  • SAFETY: Some slime coat products may permanently foul Purigen and render regeneration difficult. Do not reuse if odor of bleach/chlorine is detectable. In case of doubt, soak beads in small quantity of water and test for residual chlorine with a chlorine test kit.

Seachem 116016506 Final Thoughts

"Especially for the price!"

I wouldn't call this a master kit but a great start. The stripa are easy to use, clear instructions and I gor results in seconds. It helps get you in the ballpark with your water perimeters. The strips are able to monitor pH, nitrate, nitrite, water hardness. But it is accurate and convenient as is. No one brand is going to guarantee against this. And if it was, please click on the helpful button below.

"Love the convenience."

I used to always take a water sample to the pet store and they would teat it. If I had a complaint, I wish the color legend was printed on the bottle. If your lighting isn't right the colors will be very off. These have worked to keep my fish safe and healthy. But it turns out that is not the case. Overall, I am very happy with this kit. My 12 yrs old son wanted a fish tank so we got him 2.

"Best strips ever."

If you're looking for a quick-hit on a range of water quality these are the answer. I tested the water and the nitrates and the ph were pretty high still. Just be careful, after all these are chemicals. Comes with a lot of test strips, that are extremely easy to use and read. Then replace the caps of the bottle and test vial. But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip. 6 showing the test strip as an accurate reading.

"It's very easy to do."

But it turns out that is not the case. I wish there were a simpler accurate test for it. Wasn't labeled that way in the descriptor. I have a 55 gallon tank with a few large goldfish. They're super easy to read and seem to be pretty accurate. It shows it could be between 1-20 but the liquid shows 0. I wish there were a simpler accurate test for it.

"Best strips ever."

They're super easy to read and seem to be pretty accurate. I started wearing gloves when I use the kit. But if it's wrong at least I was proactive about it. I used to always take a water sample to the pet store and they would teat it. Takes about 5 minutes to check everything. I have not had any problem whatsoever. If I had a complaint, I wish the color legend was printed on the bottle.

"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.

"Like nuclear waste water."

The API Test Strips are a good water monitoring system for small tanks. The strips are able to monitor pH, nitrate, nitrite, water hardness. These strips are not to be trusted as a primary testing method for aquariums. This is not the right way to use this test, as it took me awhile to realize this. If I had a complaint, I wish the color legend was printed on the bottle. Very good instructions and a comparison color chart. Nice that so many things are tested with one dip in the water.
