TetraPond Bio-Active Pressure Filter, For Ponds Up to 4000 Gallons

Good replacement for my 20-year old filter.

We have a 1500 gallon pond that we've been just sort of winging it since we bought the house 4 years ago. The summers are hot in NC and the algea gets out of control. We also have a lot of trees dropping debri in the pond. We finally got in there and scooped a lot of the crap out which made the water very murky. We had a pump and filter combo from AquaSource that was so nasty to clean out. In the summertime we would have to clean it two or three times a week just to get the water to circulate through the pump. On a local Facebook group I asked what kind of pump I could use that would not get clogged up and everyone suggested the Tetra large debris pump with this filter hooked up to it. The first couple days we were pretty disappointed that we didn't see much clarity. However, after 3 weeks the pawn looks better than it's ever looked. Because the pond was so scummy and murky to begin with, I did the back flush every other day to clean out the filter and added fresh water to the pond since the backflush causes a lot of water loss into the yard. So we've had it for about a month now and the back flush option is really awesome. One thing to be mindful of is the attachment sizes of this unit are rather large (1 1/4 and 1 1/2). It's hard to find pond tubing that size locally And we also ended up having to buy a new waterfall box because our old waterfall box only had a 3/4 in max inlet. So if you end up going with this filter, I would definitely recommend buying your hosing in any other accessories you need online. We used the Tetra large debris handling 3000 gallon pump with this and it's working great.

Just installed this pressure filter earlier this week. A bit expensive, but my +4000 gallon pond is really clearing up. I was spending too much time cleaning the smaller cheaper filters.To clean this pressure filter, just turn the knob to clean for a few minutes and let it flush out the dirty water. No more scrubbing filter pads, because this filter does not have any. Even without the filter pads, this filter is trapping a great deal of dirt.Make sure you have a pump that pushes between 2,500 to 4,000 GPH. Spend more time enjoying your pond and less time with maintenance. I just received this filter, but happy with the purchase and setup.

After three days the pond was crystal clear

I have had several of these over the years and they all do the same thing. They might seal for several weeks and then you backwash and switch back to clean and they leak around the rim, losing valuable pond water and making a mess and it's either difficult or impossible to get it stopped.
