For anyone that’s used dosing pumps, it can mean either pouring your liquids into containers or popping a hole in the cap and sticking in a tube.
While these work, this great gadget from ME Corals makes it easier to simply swap the cap of your container with their version that features a John Guest style speedfit connector.
You can easily cut tubing to fit your container and also be able to easily push in your supply tube to the dosing pump. When you need to change the bottles, just swap caps and go.
Sometimes the best gadgets are the simplest. Big thanks to Tony Vargas for sharing this great find he stumbled across at the Florida Frag Swap.
