XEOGUIYA First Impressions

"Helps keep my fish happy."

It does take some time though to actually get it done. I take every precaution about the chlorine, and trust the strips for everything else. Accurate results and much much cheaper than buying from a pet chain. Easy to use, a good quantity and quality for the price. But just for a quick check, its hard to beat these test strips. The strips are able to monitor pH, nitrate, nitrite, water hardness. Very easy to use and very easy to read test strips.

XEOGUIYA Final Thoughts

"Was good for 3 years."

I found running all the tests took me around 10 minutes. The stripa are easy to use, clear instructions and I gor results in seconds. 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. You never want to wait too long and the tank crashes and has major problems. If you're out for speed, but with less accuracy get the dip tests. I take every precaution about the chlorine, and trust the strips for everything else.

"Was good for 3 years."

This is no different so I wouldn't knock this product for that. These strips are not to be trusted as a primary testing method for aquariums. If your lighting isn't right the colors will be very off. The rest of the test in the kit are much easier to use. The strips are able to monitor pH, nitrate, nitrite, water hardness. My 12 yrs old son wanted a fish tank so we got him 2. Comes with a lot of test strips, that are extremely easy to use and read.

"Hope this was useful."

I started wearing gloves when I use the kit. I started wearing gloves when I use the kit. It's quick and easy and can give you an alert if something may be going on. They show results, what is safe& not safe and what to do if not safe. It's difficult to tell if all the test sites on the strip are accurate. Dip it in the water horizontally and keep it horizontal and read it against bottle. I respect a company that backs their product.

3. NYOS Phosphate (PO4) Reefer Aquarium Test Kit

NYOS First Impressions

"FIVE STARS for sure!"

It you take it to a local fish store. Every test I do takes just a few drops. They showed the same results as these for the sites they had in common. Well I found out why they were gulping so bad. This is not the right way to use this test, as it took me awhile to realize this. These helped me check the levels and they were easy to use. Definitely recommend this test strip for anyone who has a Betta fish as a pet.

NYOS Final Thoughts

"Love the convenience."

Well I found out why they were gulping so bad. Before, I brought water into a pet store, but kept seeing no signs of improvement. Not really sure if there is a way to fix that though. They show results, what is safe& not safe and what to do if not safe. Then put the cap on the test vial and invert it several times. It does not test ammonia but that's clear in the description and bottle. This is a good kit so much more accurate and easy to figure out how to use it.

API Final Thoughts

"I really enjoy this kit."

Also, I'd avoid Tetra's strips to be honest- the reviews speak for themselves. If your lighting isn't right the colors will be very off. Besides these few flaws I have to say it's a great starter kit. These are working very well for me. It you take it to a local fish store. You mostly find them using API also. To test it, I bought a 5 pack of 5 site test strips from Petco.

5. NYOS Calcium (CA) Reefer Aquarium Test Kit

User Ratings: 48 6

NYOS First Impressions

"Helps keep my fish happy."

Having the key on the bottle is very helpful, it won't get lost. 6 and run a high pH you will see it could actually be 7. It helps get you in the ballpark with your water perimeters. I found running all the tests took me around 10 minutes. The caps do leak a tiny bit on the tubes. So I got these to try and I love them. Nice that so many things are tested with one dip in the water.

NYOS Final Thoughts

"+1-800-526-0650."

It was also kinda hard to get exactly 5ml Into the tubes. I cut each strip down the middle so that I have even more tests. The stripa are easy to use, clear instructions and I gor results in seconds. I wouldn't call this a master kit but a great start. Their Whisper 1-5 filter cartridges have skyrocketed in price and become a scarcity. Besides these few flaws I have to say it's a great starter kit. But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip.

"FIVE STARS for sure!"

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.

They quickly shipped me a new product. I used to always take a water sample to the pet store and they would teat it. The key is that you are looking for changes. This is not the right way to use this test, as it took me awhile to realize this. Just dip the strip in the tank water for two seconds, then read right away. The test strips work as advertised. The strips are able to monitor pH, nitrate, nitrite, water hardness.

"Bought the 100 Count."

It's really accurate and makes me feel like I'm a scientist while doing it. These have worked to keep my fish safe and healthy. All bottles clearly labeled and tell you how many drops. Comes with a lot of test strips, that are extremely easy to use and read. While using these weirder chemicals, it worries me a little bit. But if it's wrong at least I was proactive about it. Always nice to get something extra!

9. 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.
  • Age Range Description: All Stages
