Just reading the manual of a Reverse osmose membrane: "membranes are packed with a little quantity of antibacterial solution, manipulate with adequate ventilation...." Am I dreaming ?

Those are acclimated for more than 8 weeks and laid eggs once, water changed regularly ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
