Rated 5 out of 5 by Watercolors Protector Great for Lilly and Pumps
This is great for keeping koi from nosing their way into lilly roots. Additionally, it assists with spawning when eggs get inside keeping koi from eating. The netting material is similar to that of a fish holding cage or more open net: It is not a fine mesh which keeps out everything/muck. I have been using these to hold my Laguna pumps, which are encased in a cage. Alone, muck accumulates quickly on the exterior of the pump cages. I have been using filters made out of buckets to keep plants, etc. from plugging pump cages, but muck accumulates so much that it is very heavy and difficult to remove for cleaning. Placing the caged pumps within these protectors have proven to eliminate problem with plants and muck clogging. I also place several pieces of filter material around the pump within the bag. If using a pump having an exposed inlet, it will be necessary to wrap the pump with filter material to prevent muck and plants from jamming the fan assembly. The pumps are easily removed by lifting the tie. Should you notice a reduction in water pressure, simply lift the bag up & down several times and try to place where it is not surrounded by muck (or clean your pond)!

Rated 1 out of 5 by The5thbeatle It's a great idea, but....
I thought the concept of putting a submersible pump in a bag that acts like a pre-filter was a genius idea, so I got one for each of my two pond pumps. In a matter of hours I was seeing some real problems with water flow, and by the next day I had to pull the pumps (still inside their bags) to see what the problem was. The bags were so gunked up with debris, that it effected water flow, so I took the bags off, and immediately the situation improved!
