Good news. After one last try of my going nuts over the bubbles and noise of air in the canister, I opened it up, Filled it to the top AGAIN, and quickly closed it again just to get the noise to stop and it was fixed. I may never open it up again. lol. Thanx for all the suggestions everyone.
I think they're both pretty easy although I will admit the xp3 feels a little better to deal with when it comes time to open them up and mess with the media. The magnum I feel like I have to take it off the tank to deal with it which is just a pain in the ass. Much easier to just disconnect the xp3 and roll with it.
