I have this remedies used not as Dübger but in overdose as "algae-EX". Despite the warnings on the bottle, not the means to dose over, I have found nothing harmful - have died except for the fact that algae (not all, but most). Plants and trimmings (Neons, armored catfish, shrimp also) have come apparently completely unharmed by the treatment. Have the means for a week at a dose of 4 ml per 50 liters used (in a 200l tank). Of course, should one be also known the cause of the algae so that the algae do not grow anew after the end of the administration of EasyCarbo. For me it was a Nährstoffunterverorgung the plants, now I fertilizing and it looks much better! So even for this misuse a clear recommendation :)!
