Pondmaster 02217 PMK1700 Pump-Filter Kit

I would recommend this pump set to anyone with at least a 50 gallon pond. The pump has more than enough power to push the water up for our waterfall. The downside.. the set is very light and does tend to float. Therefore you must weight it down with a rock or something. Other than that, the pump is perfect for our needs.

The pump and filter set work great, and have done wonders cleaning up my pond. However, there are several issues the detract from the product.First, the fountain attachment does not include any kind of ball joint or adjustment, which every other similar device I have owned has included. This means you need to find a level spot at the correct depth to place the pump, which is not an easy task - I ended up just hooking the pump up to my waterfall and leaving out the fountain part. Not a surprise, but it was a little disappointing.Second, the filter sometime floats. There doesn't seem to be much rhyme or reason, as it will run fine for days with the filter staying on the bottom, then one day I will go out to find it floating at the surface (with the pump still running). Regardless of the reason for the spontaneous flotation, some built-in ballast would remedy the situation. Placing a rock on top of the filter has helped, but even that occasionally fails to keep the filter on the bottom.Other than those two issues, though, I have been happy with the performance of the pump and filter.

We use this filter for our koi pond and it works great. It's been running for at least 2 years nows. You do have to put a brick or rock on the square part to hold it under, but that's not a big deal for us, as we have several rocks. We also use bricks to keep it from moving back and forth. Makes a nice arcing water spout with pleasant noise.

Find this pump very useful in my koi ponds. Bought two as a matter of fact. Love the various heads that came with them. Does not float at all.

I've gone through several of these type of filter/pump systems for my backyard pond. This one worked well for about a year, then had to replace the pump. I expected that. I'm using a different brand/type now, and getting the same sort of results. I just wished they weighted these things so that they would sit at the bottome of the pond without having to use rocks/bricks to keep them there.
