So just wait for his pure tilt and happy does not work because it has led me to no visible reduction of brush algae. It works well not directly abtötend the brush algae, but their growth and multiplication. I have used it and at the same time on stones (take out and wash leftovers!) The brush algae and plants (generous cut) away. When I'd brush algae reddish, stubborn deposits are struck me on the discs, these are probably intermediate stages in the Pinselalgevermehrung. Under Redoxin treatment I have removed this and it came back significantly reduced. A second treatment and the toppings did not return and the brush algae also stayed away.
Redoxin with one has the chance to be thus more quickly than the algae can grow and the growth rate is also significantly reduced. If you use this to their advantage by mechanical removal or by water changes may be the goal of the stubborn algae come for a long time to get rid of.
A negative effect on fish, snails and shrimp, I could not tell.
