API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

Received one with a slight flaw.

Broke both of the tubes that came with my test kit and these are exactly the same. Survived shipping due to extreme caution of shipper (was wrapped in multiple layers of bubble wrap and packaged in a large box).

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

I like the convenience of the nearly instantaneous results of using the test strips. However, the strips are expensive. When starting up a new aquarium testing needs to be rather frequent until everything is settled down and stable. You will run through a bottle of test strip in no time. So, until the aquarium is established and stable, it is by far more economical to use the test tubes and reagents, messy and time consuming as it is. Once stable, weekly testing with the strips would be great.

It helps to control the nitrate in tank keep nitrate in check

Perfect stadard API test tubes. Came wrapped in simple plastic, no bubble wrap or box.

I expect to come in a box but it came in bag no box

These are a great product in theory. The labels have always been great- as has the seal of the vials. HOWEVER I have ordered these several times because they break SO easily. Do yourself a favor and either get a test tube rack for these or plastic/acrylic tubes or youll end up having to put these on subscribe and save!
