Little success in Slug Control

With new plants I have introduced these pests in my hitherto snails Free Aquarium. As my Netzschmerlen this plague were not Lord and I Absammeln with, of course, also did not arrive on time to always new worm, I have finally decided on a chemical agent.

That means I have the first time dosed exactly as directed and paid attention to the application intervals. The result was not satisfactory, since only very small snails were killed, the greater, from about 3-4 mm in diameter appear to be immune. And just the larger snails are indeed that proliferate always merrily.

So I will try again, but this time have this means slightly higher dosing. That has harmed neither the fish, the plants nor the worm! After the treatment was completed, I have repeatedly carried out careful partial water change, but since then a slight algae problem, which are but certainly get my algae eaters soon under control.

My Conclusion: next time I'll take my money for this product is to spend rather invest in living Schneckenvertilger!
