API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

Perfect

These are the exact replacement for the API test tubes. Just wish they were a little bit thicker glass.

Tubes were api 5ml, but didnt come In any sort of box or container other than bubble wrap

Item as advertised

Received one with a slight flaw.

Received them quickly and was a good price.

Shipped and arrived fast w/ Prime Membership and test tubes were in great (new) condition. Happy buyer.

Testing aquarium tank water

I broke a test tube from the original API Test Kit. So I ordered these. I was surprised that the lids on these fit much better than the originals. Now there is no fear of getting covered with water and chemicals while shaking a test tube!

These were shipped with no box, even though is box is shown. Fortunately, none were broken, but that should be made more clear.
