Dude was that Alligator Adventures in Myrtle Beach? I'm from Charlotte as well and I was just there on Sunday! Oh, and sweet filter. I actually just listened to a BN podcast. My understanding is you can use the filters until they get gummed up. In other words it will be obvious when they need to be changed. I think it all depends on what you push through them. Look it up, but I think you want to keep those filters wet if possible.
