So I went downstairs around 9am to go dose some AF products into the tank while lights are off..and for some reason, there's water on the floor near the tank. Of course i panicked and checked the tank to see if it's leaking, but nothing. Then I thought since it rained maybe it's from the outside. Nope. Grabbed a flashlight and went around the side of tank, saw another puddle by my cal reactor. Turns out the Kamoer dosing tubing was leaking. Good reminder to always maintain and check over all equipment every few months. Just placed an order for a new roller and tubing. Good thing I didn't go downstairs at like 1pm!! Lesson learned
