I bought a sunsun canister off of amazon and its not Priming!!! Ive pushed the blue button and filled the canister up with water and it still doesnt work. Ive pushed the button like 50 freakin times already!!!! I really need some help, do you think its because there is slack in the tubing? This thing is like an exercise trainer, can I please get some help??
Thank you very much in advance
