Ideal for professionals seeking superior water quality and sustainable pond health.

## Description

Pond Filter Media Evolution Aqua K1 Micro Media 50 Litres Code: K1MICRO50L K1 Micro is specifically designed for use in bead filters conventional pond filters and aquarium filters. K1 Micro has the same wheel shaped design as K1 Media but it has an increased protected surface area of 950 m2 per m3. The wheel shaped structure of K1 Micro is designed specifically to create the most effective environment for the nitrification process to take place. As K1 Micro media matures bacteria colonises in the “quiet areas” of each piece of media helping to improve nitrification / de-nitrification. This enables a well-balanced biological equilibrium to be sustained in your pond to keep fish healthy and the water crystal clear. The small size of K1 Micro makes it ideal to be used a replacement for beads in a bead filter. Not only will the vast 950m2 per m3 protected surface area maintain a bio-film that helps to improve nitrification water quality and clarity but K1 Micro can offer many more benefits: Increased protection for the bio-film K1 Micro retains the bio-film within its wheel shaped structure. Improved solids handling A static bed of K1 Micro packs tightly together with areas for solid particles and fines to be captured helping to reduce TDS levels. Increased flow rate K1 Micro allows enough water to flow evenly through media rather than tracking around a “clump” of beads. This means that flow rates are improved when using “like for like” pumps. Reduced back pressure The improved flow also reduces the back pressure or resistance inflicted on the pump. In turn this improves the pumps’ efficiency and may even result in the need for a lower rated pump which will ultimately save you money! Improved cleaning During a cleaning process the bio-film remains protected within the K1 Micro. Semi buoyant media K1 Micro is a semi buoyant media which makes it ideal for a bead filter. Evolution Aqua K1 Micro Filter Media Product Summary: 950 m 2

Review: Game changer in filtration - Seen a few videos online and decided to design a system that suited the ponds needs. 120L barrel, makeshift air manifold, a couple of tank connectors and most importantly 50L of K1 micro. The bubbling video was taken during the cleaning process, I actually use the media static rather than moving bed but I do have the option to use it as a moving bed biological filter once the media is properly matured. So realistically I’m only reviewing this as a mechanical static media for now and it’s absolutely brilliant. It catches all the fines, even those that you’d only see under a microscope and no more taking out stinky media from a box and hosing it off, it’s made maintenance 100 times easier and the filtration is 100 times more efficient. So happy I have switched over to this, should have done it ages ago. If you are thinking about it…. DO IT!

**Q: How much K1 would be needed for a110 gallon tank?**
A: Hello,
K1 Micro Media is typically used in Evolution Aqua K+ Advanced Filters and are rated on filter and pond size. Pond size and bio load would likely come into play with how much would be needed. I need more information to be able to help investigate this. You could also try reaching out to the manufacturer for further information.
