API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

Clearly marked for accurate measuring. However, the tubes are a bit small for the conventional test tube rack and fall to the bottom. They should indicate the dimensions on the box so an appropriately sized rack could be used. Otherwise indispensable.

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).

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!

Delivered as shown and described

Identical to the tubes that come with the API Master Test Kit.

Original came broken but was replaced for new ones within 24 hrs. Overall good same as original

exact replacement for those that came in the kit.

Looks exactly like the tubes from my master kit. Perfect!

Tubes are great for testing water, however, the tubs come in bubble wrap and not in a box. I was looking forward to having a box for easy storage of the tubes. Misleading because the picture shown is of a box indicating 6 tubes. The tubes are stored loose and not protected.

I love API products, except I have to agree with other buyers. After having & using tubes for a little while, the tops do tend to stick (even after cleaning them right after testing) I have had 2 break in my hand. The add is MISLEADING it shows an API BOX of 6 tubes, but they came wrapped in plastic together. WHY WOULD YOU SHIP 6 FRAGILE TUBES IN A BOX WITH A 16 fl oz BOTTLE & A 8 8 fl oz BOTTLE WITH NO PROTECTION TO KEEP THEM FROM ALL MOVING AROUND DURING SHIPPING. THANFULLY THE TUBES MADE IT ALL IN 1 PIECE. ITS JUST THE POINT. I usually never write bad reviews, but this just didnt make any sense to me. WHY?? Didnt give a 5 star only because of packaging and did not come as photo shows.
