This trip out I decided I would try to investigate the effectiveness (or lack there of) of my pre-filter setup in my gravity system.
I'm currently using a Platy CleanStream cartridge, but also used the exact same type of system with the Frontier Pro filter.
With the Frontier Pro, I just put a 3/4" piece of hose on the intake (inside the bag) to facilitate a silt settling area of water that would remain in the bag. With the CleanStream, I just left the long hose barb sticking up in the bag.
Here is an example of what gets left in the bag from clear creek water. It would probably be more efficient, the longer it was left to settle.
To catch the stuff that doesn't settle, the Frontier Pro comes with a few little round chunks of fiber-fill looking stuff that goes between the intake parts. In my CleanStream bag, I put a chunk of the same stuff in between the two hose barb adapters that screw together on the inside and outside of the bag.
Here's what it looks like after 3 long weekend trips… same water conditions.
Ok, that's all. Thought it might be mildly interesting.
Edit:
Sorry for the lighting in that last pic. Should have used a flash. -
