Velda 126463 Compact Filter for Ponds up to 5000 L Including Pump, 13 Watts, UV-C, Floating Combi Filter 2500

I am using this as a secondary filter as it floats in the center of the pond and acts as a fountain . water is clearing quickly and the fish seem to like it and are more active. very long cable but came with molded 2 pin continental type plug which had to be cut off and UK plug fitted. All in all so far very pleased with this purchase.

Excellent product. We have a 4500 lite pond with no filtration, only a few aeration plants, and only a few water lilies (therefore much of the surface area is free from plants).We have 4 large goldfish and 9 very small goldfish, so quite a high biologic load.The pond was new in October, but had become green and murky over the months (October - June). Within one week, this filter had greatly improved water clarity, and the splash features (which is like a fountain!) is an added bonus as the oxygen level in the pond water has shot up to a much healthier level.The aesthetic of the filter is great, with only the dome visible above the water (however more is becoming visible as the water quality increases).Initially, weekly cleans were necessary, which is a simple process. Now, it is only necessary to clean every second week. Best to place a bag in the pond and place filter inside for removal for cleaning, otherwise waste will wash from the filter into the pond, undoing its work.As other users have found, the mesh is quite coarse. I added a thin layer of garden frost fleece under the mesh to aid fine sediment entrapment. The water flow remains the same, so i assume no additional stress is placed on the motor having done so.I would give 5 stars if this modification was not necessary.

My 6000 litre pond was VERY dirty after a period of neglect! Couldn't see white fish even when they were at the top! This little unit made a noticeable difference in a few days. Had to clean it fairly regularly, but boy, it did the job! After a week, I wrapped white filterwool around the unit and ran it. This really got the pond clearing. Needed a lot of cleaning, but my pond WAS dirty! Two weeks later and I can see the bottom of the pond, the fish seem livlier, maybe due to the induced oxygen this filter unit creates, and all I can say is this is a great little filtration product. It also has a nice little "fountain" effect due to its design. Very highly recommended indeed. So glad I invested in it.

This has been in my pond for about 4 weeks and it is nothing like clear . I’ve had one of these before . A smaller one but it was superior to this one. Confused !!!

Pond lovely and clear, easy to clean, great buy, great for small ponds!

Arrived promptly and only setup required was adding charcoal (supplied) to the bottom area and electrical installation. The external fabric which surrounds the foam filters is a sort of mesh bag, fixed at the top my a bungee cord, which I imagine will be performance to remove and replace when wet. However, it is attracting the fine sediment that our fish kick up when in feeding frenzy mode. So far, I have found the most effective way to take it out for cleaning is to put a large bucket under it and to lift it out so the sediment can't float away. I have then just brushed the sides down into the bucket with a bit of a squeeze to get stuff out of the foam filters. Thank you to the reviewer who suggested an old pair of thick tights as a filter as I have been able to return the clear water to the pond after straining through the same! I like the relatively gentle effect of the water trickling over the top and so far, had none of the issues of crud in the fountain pipe restricting or redirecting water flow and squirting water in all directions that I have previously had with the more traditional 3-in-1 hoselock type models. Still early days as only been on operation for a short while.

I think this is probably the best filter I've ever had. Clear water always.

filter sponge too coarse, would have been better with a finer grade sponge. majority of particles are not caught in sponge and are re-circulated. searched internet for replacement sponge without success. concept is good. quality is good., but not effective enough for me.
