Review on 🐠 Hygger Aquarium Dosing Pump - Advanced Programmable Auto Titration Pump for Marine Coral Tanks with 4 Channel Dosing Heads and 8 Titration Long Hoses by Justin Jefferson

I'm giving 5 stars because I can't give a 4.5. Works well. I'm only a few weeks old but it's working as expected. So far my only complaint is that programming is intimidating. It could have been a bit more user-friendly, but I'm still happy with it. The instructions are a bit difficult to understand as some of them get lost in translation. Be sure to follow the instructions in the manual. You'll need to calibrate it, so make sure you have something on hand that measures exactly 100mL. I will update when I use it more.
