Hi everyone. I have posted a few questions before and have not had luck with getting any advice. So, I've relied on other sources who may be better or less informed. I have a used canister filter I bought a while ago, and I am trying to at least start it for a while with what the previous owner gave me in supplies. I emptied the canister and cleaned it all, but can't remember the order which they had it. Its a MArineland 360 FYI. I do know for certain that at the very bottom was the basket (the only basket that has a flat bottom without holes for waterflow-so I think its meant to be at the bottom) with the foam I think it's called- its black, very porous. Also I have a basket with bio-balls, and ceramic rings, and ONE polishing pad. I don't know which order to put them? Also, I have the filter just below the surface of the water by about a foot, instead of the recommended 2 feet. How will I start the filter? I don't know exactly. THe instructions say to push prime button twice, but I don't know if I do that before or after I plug it in. Thanks in advance!
