Clear water, fast shipping, easy to install Ordered this filter from 123ponds and it was delivered in 2 days. It was easy to connect as it included some different fittings. Instructions were easy to understand. It took about 10 minutes and the filter was running. My pond is about 2000 gallons and was terribly green so it took about 3 days to really clear the water but it has been crystal clear since.
Pros:clear water

Best pond filter ever I have been through a lot of koi filters .... You could always build a filter but that would cost a bit of money.... I find that this pond filter is one of the easiest filter to use . Took me no more than an hr to set up and get it running...
Pros:Great filter
