Their research has resulted in a patented bio-carrier that provides both high surface area and a non-clumping design. Performing both mechanical and biological filtering, cleaning of accumulated solids is accomplished via “cyclonic” power backwashing of the media. This process both reverses the flow direction and spins the media, resulting in more thorough removal of debris. Designed for high flow rates, heavy fish load with high feed rates, the Ultima II filter is a popular choice for many koi keepers and water gardeners.\u003c\/span\u003e\u003c\/p\u003e\n\u003cbr\u003e\n\u003cp\u003e\u003cspan style=\"font-weight: 400;\"\u003eUltima II filters are available in a number of sizes to accommodate various  pond sizes and fish loads.\u003c\/span\u003e\u003c\/p\u003e","brand":"Aqua Ultraviolet","offers":[{"title":"1000 \/ 1.5\"","offer_id":34057468215341,"sku":"A50073","price":998.75,"currency_code":"USD","in_stock":false},{"title":"1000 \/ 2\"","offer_id":34057468248109,"sku":"A50079","price":1196.93,"currency_code":"USD","in_stock":false},{"title":"2000 \/ 1.5\"","offer_id":34057468280877,"sku":"A50019","price":1533.52,"currency_code":"USD","in_stock":false},{"title":"2000 \/ 2\"","offer_id":34057468510253,"sku":"A50017","price":1643.23,"currency_code":"USD","in_stock":false},{"title":"4000 \/ 1.5\"","offer_id":34057468575789,"sku":"A50003","price":2072.9,"currency_code":"USD","in_stock":false},{"title":"4000 \/ 2\"","offer_id":34057468641325,"sku":"A50004","price":2368.01,"currency_code":"USD","in_stock":false},{"title":"6000 \/ 2\"","offer_id":34057468674093,"sku":"A50007","price":2639.94,"currency_code":"USD","in_stock":false},{"title":"10000 \/ 2\"","offer_id":34057468706861,"sku":"A50011","price":3519.87,"currency_code":"USD","in_stock":false},{"title":"20000 \/ 2\"","offer_id":34057468739629,"sku":"A50119","price":4241.9,"currency_code":"USD","in_stock":false},{"title":"30000 \/ 3\"","offer_id":34057468805165,"sku":"A50301","price":7693.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0319\/4961\/9245\/products\/UltimaII1.jpg?v=1587677966"},{"product_id":"pondmax-pressure-filters","title":"PondMAX Pressure Filters","description":"\u003cdiv class=\"jps\"\u003e\n\u003cstyle\u003e.jps{--card:#F1F7FA;--ink:#14242E;--inks:#485A66;--indigo:#0E3A52;--indigod:#0A2A3C;--koi:#0892B5;--line:#CDDEE8;font-family:'Inter',system-ui,sans-serif;color:var(--ink);line-height:1.65;max-width:1180px;margin:0 auto}.jps h2,.jps h3,.jps .serif{font-family:'Shippori Mincho',Georgia,serif;font-weight:600}.jps .ey{font-size:12px;letter-spacing:.2em;text-transform:uppercase;color:var(--koi);font-weight:700}.jps .lead{font-size:18px;color:var(--inks);max-width:62ch}.jps .band{background:linear-gradient(180deg,#DCEAF0,#C4DCEA);border-radius:16px;padding:30px 34px;margin:0 0 16px}.jps .band h2{font-size:30px;margin:6px 0 10px;color:var(--indigod)}.jps .trust{display:flex;flex-wrap:wrap;gap:10px 22px;align-items:center;background:var(--card);border:1px solid var(--line);border-radius:12px;padding:13px 20px;margin:0 0 24px}.jps .trust span{display:flex;align-items:center;gap:8px;font-size:13.5px;font-weight:600;color:var(--ink)}.jps .trust svg{width:18px;height:18px;color:var(--koi);flex:none}.jps .feat{display:grid;grid-template-columns:repeat(2,minmax(0,1fr));gap:16px;margin:24px 0}@media(max-width:560px){.jps .feat{grid-template-columns:1fr}}.jps .fc{background:var(--card);border:1px solid var(--line);border-radius:12px;padding:20px}.jps .fc svg{width:30px;height:30px;color:var(--koi);display:block;margin-bottom:10px}.jps .fc h3{font-size:16px;margin:0 0 5px;color:var(--indigo)}.jps .fc p{font-size:14px;color:var(--inks);margin:0}.jps .specwrap{overflow-x:auto;border:1px solid var(--line);border-radius:12px;margin:12px 0}.jps table.spec{width:100%;border-collapse:collapse;min-width:560px;font-size:14px}.jps table.spec th{background:var(--indigo);color:#fff;font-family:'Shippori Mincho',serif;font-weight:600;text-align:left;padding:10px 12px;font-size:12.5px}.jps table.spec td{border-top:1px solid var(--line);padding:9px 12px;color:var(--inks)}.jps table.spec td:first-child{font-weight:700;color:var(--indigo)}.jps h2.sec{font-size:23px;color:var(--indigo);margin:18px 0 10px}.jps .brand{background:var(--indigod);color:#E3EEF3;border-radius:16px;padding:26px 30px;margin:26px 0 6px;display:flex;justify-content:space-between;align-items:center;gap:20px;flex-wrap:wrap}.jps .brand h3{color:#fff;font-size:21px;margin:0 0 4px}.jps .brand p{margin:0;color:#BCD2DD;font-size:15px}.jps .brand a{display:inline-block;background:var(--koi);color:#fff;text-decoration:none;font-weight:600;font-size:14px;padding:11px 20px;border-radius:40px;white-space:nowrap}.jps .note{background:var(--card);border:1px solid var(--line);border-left:4px solid var(--koi);border-radius:10px;padding:14px 18px;font-size:14.5px;margin:16px 0 0}\u003c\/style\u003e\n\u003cdiv class=\"band\"\u003e\n\u003cspan class=\"ey\"\u003ePondMAX · Pressure Filters\u003c\/span\u003e\u003ch2\u003eThree-stage koi pond filter — mechanical, biological \u0026amp;
