Accurate + Affordable
Love these. Each panel produces a match with one of the colors on the bottle which hasnt been the case with some of the other brands ive used. So they’re easy to read and highly accurate. Also a better value than many others.Im so glad I got these as opposed to other brands. I was going to start using my home tap/well water because the hardness is perfect for my fish and snails but when i tested it with these strips, i was able to see that the water had small traces of copper in it which is very harmful to my pets. Had i used any of the other strips I had before, id be having a funeral right about now for all of my aquatic pals. So these are literally lifesaving 😌

Good price.
Difficult for me to distinguish the color shades, so the accuracy of my eyes are in question. I hold it in bright white light to read and that helps. If I purchased a professional testing kit it would cost more than my fish soo there’s that! My fish seem to be thriving so I must be doing something right!

Good
Works, but haven’t compared to a more professional kit so that is believing the test. Wish it tested salt content.
Honest Reviewer –
They put in hot mailbox
They stuck this in a hot mailbox, and the instructions say to keep it in a cool, dry place. Well, I tested it, and it didn’t work. It said my PH was very low, but I also have a more accurate liquid tester, and it said the pH was actually high. I had another pater brand, and it said the pH was high. So this Bacnunn is completely useless, and there is no refund except 20% off.

seems to work fine. easy
seems to work. i switched from another that had fewer indicators. i also own the liquid drops test kit which hasn’t ever really shown me anything these strips don’t, so i just use the strips. i have plants so no/low nitrates/nitrites but my ph was low.
