Algae and Co. flakes, glue and can be easily filtered out. For me, the effect is one that again strong water turbidity occur despite meticulous cleaning of the filter after the treatment after 2-3 weeks by algae. In 3.000l pond volume I am favorable to the complete change of water (3 m³) and the fish to swallow any chemistry. On each of these vials (bought several last year 5, no has delivered the promised results) is equal to the reference to post-treatments with product Y. In Product Y then is that before yet to be treated with product Z. That's me all about chemical and too expensive. Water changes and you're done. The trick with the long-life milk as an algae eater has not worked.
