Krachtige vijverfilter voor vijvers tot 40.000 liter of koivijvers tot 24.000 liter



Het sera KOI Professional 24000 vijverfilter is qua functie en design modern en koersbepalend. Plaatsbesparend en effectief reinigt het vijvers tot maximaal 40.000 liter, koivijvers tot 24.000 liter.

Het is niet alleen volgens de nieuwste stromingstechnische inzichten geconstrueerd, maar heeft naar buiten toe ook een attractieve outfit.

Het water doorloopt 4 reinigingsfases: In de fysische wordt het water eerst met een kiemen- en algenreducerende UV-C-straling behandeld. Via een stuwkamer stroomt het naar de mechanische reinigingsfase, die uit een gebogen edelstalen spleetzeef met een spleetbreedte van 200 µm bestaat. Hier hopen zich niet alleen grove deeltjes op, maar ook de door de UV-C-straling voorbehandelde en tot klonters gevormde algencellen.

Wanneer de algen dreigen te gaan bloeien (“groen water”) kunnen met enkele handgrepen onder de spleetzeef twee fijnfiltersponzen geplaatst worden, die zelfs eencellige algen uit het te filteren vijverwater halen. Mochten de sponzen niet op tijd gereinigd kunnen worden, dan loopt het water direct via een veiligheidsoverloop naar de biologische fase. Hier wordt het water eerst via een Matala-mat verspreid, met zuurstof verrijkt en sijpelt vervolgens over het krachtige filtermedium sera siporax pond, dat door filterbacteriën bevolkt wordt. Via een stuwfase loopt het gereinigde water weer terug de vijver in.

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.
