TetraPond Bio-Active Pressure Filter, For Ponds Up to 2500 Gallons

I was struggling to keep my new pond clean and free from algae and my previous pump clogged literally after 1 week. After doing some research I decided to try this filter along with a Tetrapond pump. Wow! What a difference it made in about 10 days. No more clogs in the fountain and the water clarity settled down and is easy to maintain. Very easy to clean as well. Note that this filter is MUCH bigger than it appears. I was able to hide it under an upside down half oak barrel, that now has a potted plant on it. For reference, my pond is 12 x 12 and 3 feet deep. Holds an estimated 2,200 gallons.

I have had one of these filters for around 8 years so I just purchased another one because I feel it could be at the end of its life. It is super easy to maintain and keep the pond clean. I love the backwash feature, but after turning off the pump, we take the hose out of the water else the backwash (as you turn it on and off) will dump tons of dirt into the pond. So just take the hose out and do the backwash on and off a few times until you see is coming clean at both ends. Also, we normally wash the whole filter probably every 8 weeks. We made a gigant container (a square with 4x2s) with hardware wire as the floor of that container. We dump the little white piece onto this made up strainer and hose them really well. Makes the job super easy... but you lose the good bacteria every time you do a full filter clean. We fill the filter with the pond water and works fine. My only concern eith this filter is the hoses could become lose even with clamps and i am terrified of obe day finding the pond with no water. I am trying to find better connectors that mire securely attach the hoses to the in and outlets. The filter last longer if it is covered from direct sun too. I have the pump also from Tetra and both of them work great together. Very pleased. My 7 koi fish are all happy and healthy.

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.

I just got this filter. I have it installed inline to serve as a pre-filter for my laguna water fall filter. So far, the filter doesn’t leak and works well enough as a pressure filter. No leaks so far, but I noticed that the seal is not from an o ring, but rather a plastic on plastic seal, which I can foresee problems down the line. Definitely a major design flaw, but so far it’s sealing. You must run the backflow cap, there is always water flowing out of the backflow outlet regardless of where the flow setting is. Not sure if that is an issue with mine, if it all are like that. But a couple Amazon reviews report the same thing. I put some teflon tape on the threads of the nozzles for security. This filter is made in Italy, so I have more trust in it than the other nameless filters you see on Amazon. If it had a o-ring for the main cap of the filter, I would give it a 5 stars, but it does not.

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.

This filter started out great! Was bigger, seamed to easy to maintain. Well less than 2 months we started having gasket problems. Now the upper valve continues to leak. And pours out of the valve when back flushing. The manufacture is no help either they are out of replacement gaskets and won’t get any back in until after August I am told. Don’t waste your money here! Spend a little more and get a better design.

Does great on filtering the water. Unfortunately, due to cheap plastic clamp design while clamping the top back on it snapped and broke. I only open this twice a year to clean and maintain. Should have lasted alot longer considering it is indoor and not susceptible to outdoor elements. Will look for other options going forward.

Works wonders!

After three days the pond was crystal clear

Good replacement for my 20-year old filter.

This TetraPond Bio-Active BP1500 Pressure Filter comes in a large box, weighing about 9 pounds. Everything is easy to open, connect, and start using right away, thanks to the well-written instructions included inside. The filter has a very simple design, that features an inlet and an outlet as well as a backflush. During my testing, on my 800-gallon koi, goldfish, and pleco pond, the filter was running dry without any noticeable leaks, so both the housing and connections were solid and tight-fitting. I ran this for well over a month and it did well to maintain my pond, keeping it free from algae buildup. This filter has been on the market for some time and it's a popular choice. The biggest reason why it's done well is because of the backflush feature which cut down on so much of the dirty work involved in filters that don't have one. All I have to do to clean the unit is turn the single knob to the clean position, which flushes out the entire system of dirt and debris while keeping the good bacteria remaining on the bio-activators. I use the nutrient-rich water from the backflush in my nearby garden, which provides a natural fertilizer. As the name suggests, this filter is rated for a 1500 gallon pond. In terms of the current price, this is one of the most affordable options out there on the market my experience has shown that it is a really good choice, especially for medium size ponds. Full marks from me!

We have an indoor turtle pond. About 150 gallons with 1 turtle and a few big gold fish. The turtle has access to large sandy rock suning area so is always carrying debrie back with her. For not having an ultra violet light or spounge media I was amazed at how well this cleared up the water. When I put this is we did a 1/2 water exchange and things were stirred up pretty good. We had removed a waterfall and some plant material as well. The water was horrible looking but by the next morning it was nice and clear. In the pic there may be a little haze.... had to go find the air bubbler after removing waterfall to turn water over. The 4 stars instead of 5 is that this suffers from leakage from the "back wash" port just like every other model I have owned.... but this one does it from the start..... but it comes with a stop block for the port so at least they acknowledge this flaw and provide a solution from the start. In the summer I will buy an UV chamber to add in line somewhere but for the price you really can't ask for much better. If anything happens that would change this review I will update but highly recommended so far.
