I have recently had an outbreak of snail in my 165 litre tank. Nothing new has been added to the tank for months, so I am at a loss as to where they have come from. I purchased eSHa Gastropex Aquatic snail treatment, which after one set of treatments not only semms to have had no effect on the snails, but appears to have killed my previously healthy albino cory. Can someone please suggest an effective and safe treatment ? I have brought some clown loaches to help combat them, but all they seem to be doing at the moment is hiding. Help please !!
