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.

2. ICP Analysis 33 Elemental Water Test Kit - Four Sample Kit

ICP Analysis First Impressions

"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.

Red Sea Fish Pharm Ltd. First Impressions

"Great magnesium test kit."

Not sure if the reading is 0 or more likely something between 0-. I wish there were a simpler accurate test for it. Also, I'd avoid Tetra's strips to be honest- the reviews speak for themselves. It's really accurate and makes me feel like I'm a scientist while doing it. Will definitely buy again, if we ever run out! They're super easy to read and seem to be pretty accurate. Probably won't buy again because of the bleeding issues.

Magnum Media Salinity 10ATC SR007-10ATC First Impressions

"These are just easier."

If I had a complaint, I wish the color legend was printed on the bottle. I was having trouble keeping my fish tank water looking good. They test pretty accurate when run against my chemical tests. It's quick and easy and can give you an alert if something may be going on. No issues so far, test strips work well. But after last night these are a must have for me. I've already lost one test tube cap, most likely due to my cats playing with them.

Accurate results and much much cheaper than buying from a pet chain. It's quick and easy and can give you an alert if something may be going on. First few strips I used gave an accurate ready.

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.
