"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. These strips are not to be trusted as a primary testing method for aquariums. 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. 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.

Tetra Pond First Impressions

"Quick and easy use."

It you take it to a local fish store. I tested the water and the nitrates and the ph were pretty high still. Then replace the caps of the bottle and test vial. I was having trouble keeping my fish tank water looking good. Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. Not really sure if there is a way to fix that though. It's difficult to tell if all the test sites on the strip are accurate.

If this review was helpful, please click the helpful button! This kit is extremely accurate and very well designed for convenient use and storage. This is no different so I wouldn't knock this product for that. 6 and run a high pH you will see it could actually be 7. I'm still not sure about the chlorine site. So off to buy some sponge filters I went! They showed the same results as these for the sites they had in common.

"Just sayin'."

These strips are not to be trusted as a primary testing method for aquariums. Despite what it says on the chart, oxygen at 6mg will cause fish to start gulping. Besides these few flaws I have to say it's a great starter kit. If you're out for speed, but with less accuracy get the dip tests. I'm still not sure about the chlorine site. It's really accurate and makes me feel like I'm a scientist while doing it. You never want to wait too long and the tank crashes and has major problems.

I will now test my water periodically to make sure everything is ok. If you keep freshwater fish, you will need this test kit. Will definitely buy again, if we ever run out!

"Great test kit!"

Besides these few flaws I have to say it's a great starter kit. Then put the cap on the test vial and invert it several times. This is a kit to test for my aquarium water quality. All bottles clearly labeled and tell you how many drops. If your lighting isn't right the colors will be very off. This spreads out the 6 month expiration date after opening. I don't know so much about how precise these are.

Salifert NIPT First Impressions

"This is my water."

I would not use it solely for checking nitrate and nitrites. Quantity of strips seems very good. Not sure if the reading is 0 or more likely something between 0-.

The test strips work as advertised. These helped me check the levels and they were easy to use. You mostly find them using API also. My tap water actually was really green and was a very close match to the 1. They showed the same results as these for the sites they had in common. Takes about 5 minutes to check everything. I wish there were a simpler accurate test for it.

"These strips are great."

Nice that so many things are tested with one dip in the water. If your lighting isn't right the colors will be very off. I have not had any problem whatsoever. I take every precaution about the chlorine, and trust the strips for everything else. It's quick and easy and can give you an alert if something may be going on. But just for a quick check, its hard to beat these test strips. It you take it to a local fish store.
