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.

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.

"1 dKh difference."I wouldn't call this a master kit but a great start. This test kit is easy to use and the results are easy to read. So off to buy some sponge filters I went! 6 showing the test strip as an accurate reading. Easy to use, a good quantity and quality for the price. It looks to have the slightest green tinge but is not as green as the 0. I don't know so much about how precise these are.

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.

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

"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.

"I don't know."It looks to have the slightest green tinge but is not as green as the 0. It does'not' have the same accuracy but it’s very close. I have a 55 gallon tank with a few large goldfish. These have worked to keep my fish safe and healthy. No one brand is going to guarantee against this. It shows it could be between 1-20 but the liquid shows 0. You mostly find them using API also.

"Love the convenience."My water was good to go and soon after I for fish that are doing well! They showed the same results as these for the sites they had in common. This is a kit to test for my aquarium water quality. This spreads out the 6 month expiration date after opening. Unfortunately nitrates still might be the most important test, at least for me it is. This is a good kit so much more accurate and easy to figure out how to use it. So I got these to try and I love them.
