After a week of use, I could observe during this time, like all species were growing faster than regular manner (slow-fast-growing plants) and at a dose of 1-1,5ml per 50l (according to the manufacturer's recommendations). Today at WDW I see a dead neon on the ground. His Todursache has with the dosage emulate what this product !!! Therefore, I advise everyone to reduce the dosage. Now i am going to conserve only 0.5 ml 2 × day at the fish on the day. Whether it is effective against algae, will be seen in the near future. An update follows!
