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.

"I really enjoy this kit."

So off to buy some sponge filters I went! I take every precaution about the chlorine, and trust the strips for everything else. Strips were always stored in a sealed dry place. This test kit is easy to use and the results are easy to read. They quickly shipped me a new product. But it is accurate and convenient as is. Tank lids, water additives and more have seen the same effect.

Nutrafin A7815 Final Thoughts

"Used the same kit before."

I found running all the tests took me around 10 minutes. These have worked to keep my fish safe and healthy. The API Test Strips are a good water monitoring system for small tanks. In my opinion they arent quite as accurate as master test kits either. Will definitely buy again, if we ever run out! Overall good value for a small hobbyist aquarium owner. But if it's wrong at least I was proactive about it.

"He perked right up."

I started wearing gloves when I use the kit. But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip. This is no different so I wouldn't knock this product for that. These have worked to keep my fish safe and healthy. The price is great for all these essential tests! Overall, I am very happy with this kit. Will definitely buy again, if we ever run out!

  • Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums 250ml
  • TANK STABILIZATION: Seachem Stability will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: "new tank syndrome".
  • TREATMENT: Stability is formulated specifically for the aquarium and contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrite, and nitrate.
  • BACTERIA GROWTH: The necessary conditions for the growth of Stability's bacterial strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the unknown death of an organism), Stability simply becomes more effective.
  • USE: Shake Seachem Stability well before use and turn off UV/ozone filter. Use 1 capful (5 mL) for each 40 L (10 US gallons) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 US gallons) daily for 7 days. Fish and other aquatic species may be introduced at any time as long as the dosage is maintained for 7 days.
  • SAFE: The bacteria employed by Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Stability is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of overuse.

Seachem 116012607 Final Thoughts

"Simple and easy to use."

To test it, I bought a 5 pack of 5 site test strips from Petco. Takes about 5 minutes to check everything. This spreads out the 6 month expiration date after opening. I tested the water and the nitrates and the ph were pretty high still. Also, I'd avoid Tetra's strips to be honest- the reviews speak for themselves. I was having trouble keeping my fish tank water looking good. I have not had any problem whatsoever.

"Great value, Speedy ship!"

But it turns out that is not the case. Probably won't buy again because of the bleeding issues. This test kit is easy to use and the results are easy to read. Wasn't labeled that way in the descriptor. I'm the test strip came in handy it saved all of my fish. These strips are not to be trusted as a primary testing method for aquariums. It does take some time though to actually get it done.

"Great test kit."

It does not test ammonia but that's clear in the description and bottle. I would not use it solely for checking nitrate and nitrites. But, I will continue to order Tetra's 6 in 1 until someone makes a better test strip. I'm the test strip came in handy it saved all of my fish. Very helpful for checking the water in our tank. I tested the water and the nitrates and the ph were pretty high still. If you're out for speed, but with less accuracy get the dip tests.

"So they're measuring!"

I have a 55 gallon tank with a few large goldfish. They're super easy to read and seem to be pretty accurate. I like API products and find them the most accurate. My results are never all over the place like other reviewers. But after last night these are a must have for me. My 12 yrs old son wanted a fish tank so we got him 2. Overall good value for a small hobbyist aquarium owner.

"Gives me peace of mind."

While using these weirder chemicals, it worries me a little bit. It was also kinda hard to get exactly 5ml Into the tubes. I'm the test strip came in handy it saved all of my fish. I have not had any problem whatsoever. Dip it in the water horizontally and keep it horizontal and read it against 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.

"Hope this was useful."

Always nice to get something extra! Wasn't labeled that way in the descriptor. Then put the cap on the test vial and invert it several times. While using these weirder chemicals, it worries me a little bit. Well I found out why they were gulping so bad. You never want to wait too long and the tank crashes and has major problems. Best price, best quality, fair accuracy and better than most brands, etc.

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.
