penn-plax cascade 1200 canister filter question PLEASE HELP!

[LMBDave]

How can u tell the difference between the input and the output? I dont want to hook it up backwards. I know one tube is blue and the other is black if that helps...please help!

Also, how do u prime these filters?

Do u have to fill the canister with water before u turn it on?

Thanks for helpin out a noob.

blue is IN Black is out it should be marked under under each one hard to see but mine is marked. to prime you just put the tubes in your tank push down a few times on the large prime button and you will see air bubbles coming out the tube as the filter is filling with water then just plug it in AFTER it has finished filling and your done just add some water back to the tank to refill it to replace the water that went into the filter and make sure the flow control levers are facing straight up in the 12 oclock position that means they are open if the are down in the 3 oclock position that means no water in or out of the filter.

Yes those in/out marks and colors can be hard to see inside a stand. If you have a label maker, make up some in & out tags and stick them on the canister side and hoses. Makes it much easier for servicing. And beyond that, I made tags for all of my cords into power strips, for ease of ID'ing at service time.
