"We have a pond that is now about 5 years old, and is about 2500 
gallons in size.  We had tried two different filter systems (one with a 
small UV light) during the first 4 years and they never were able to keep 
our pond clear. The clean-up was also a long and messy job of rinsing 
filter elements. A friend of ours was building a pond in his yard and even commented that he wanted to make sure his didn't look like a "slime pit" 
like ours did!

After that comment I started looking around for a solution and my wife 
found your web-site. I did quite a bit of investigation into the Challenger Filters and decided to try it.  After installing the Challenger filter, with a turbo-vortex and UV light, our pond has remained crystal clear through 
all seasons. The filter cleaning is now about a 10 minute job every week 
or two and literally can be down without getting my hands dirty. The fish 
are as healthy as they have ever been... The whole system was not cheap, but the results are worth it, given the frustrations and poor filtering with previous setups. No more slime pit."

"After all else failed to clear my pond your challenger did the 
job in two weeks.  Easy to maintain & a quantum leap above everything 
else out there."

"This system looks like it's going to be a huge improvement 
over our previous system.  We seem to be taking more debris 
out of the water in a shorter period of time than ever before. We've only had it up and running a short while, but I look forward to seeing what this system will do for us once the biological filter is established."

"I PURCHASED A CHALLENGER 60 SYSTEM LAST 
SUMMER.  BRETT AND SALES STAFF WERE HELPFUL. 
SOME MINOR PROBLEMS WERE ADDRESSED AND CORRECTED. 
I RECOMMEND THIS FILTER FOR 5000 TO 10,000 GALLON PONDS. ONCE FILTER GETS GOING, WATER IS CRYSTAL CLEAR!"

The Challenger #50 filter is installed, running, and has made a 
dramatic improvement in the quality of the water. It was simple to install, and everything worked well the first time.
I have an unusual configuration, as it is replacing another 
type of filter, and it is doing a good job.

I got everything installed and running over the weekend and the water is clearing up nicely. I should be able to see the bottom in a couple days or so. It looks like this new filter system will save me a couple hours every other weekend that I would have spent cleaning my pond!
