Evolution Aqua K1 Media - 50 Liters

Practical Garden Ponds is a good option for those looking to purchase K1 filter media. In the FAQ section, Practical Garden Ponds explains that K1 filter media is not compatible with sand filters, so it is important to purchase a pond filter that is designed to work with this type of media. This is important due to the design of laterals in sand filters, which have very small perforations that prevent the sand from escaping. Therefore, even if you replace sand with good K1 filter media, your filter will still clog more frequently with dirty pond water. The key takeaway is that it is important to choose the right filter for your pond. As for the product itself, the reviews seem to be mixed. Some customers seem to have had good experiences, with comments like "great product" and "used it in my pond bio filter". Others seem to think that the product is too small, with one customer commenting that "it's like K3. Not K1". Additionally, a few customers have not yet formed an opinion, with comments like "no comment on this product yet". In terms of pricing, customers seem to be quite happy with the value for money, with one customer commenting that it is a "fantastic company, amazing price". Overall, Practical Garden Ponds seems to be a good option for those looking to purchase K1 filter media, but customers should be sure to choose the right filter for their needs.
