### ⭐⭐⭐⭐⭐ Perfect for my needs
*by H***S on 16 June 2020*

Running a medium sized reef tank, I needed some additonal tubing for my dosing units and also some replace some older tubing that was under the salt water line. Using this tubing was easy, cut nicely without any breakages or tears. I have been able to use this quickly for my airline for "bubble scrubbing" without any issues. It hasnt leached anything into the water and can verify this via ICP-OES tests from triton. All in all, very very impressed. Just wish they had more in stock as I need more :)
