Hydra.....Hydra.......OMG ...... i hate them little @#$#'s.... lol. but seriously i havent had a problem with them is a couple of years.... but i have to agree with Mikie.... using fluke tabs is the best way to get rid of them.... Of course.... breaking the tank down, bleaching the @#$# out of it works too!! Sorry for some reason im into "extreme" ways of doing things today!! Must be the new snow thats just messing with my head... But my fluke tabs always dissolved too... maybe the soft acid water does that... i dunno.???? Anyways.... just my 2 bits worth Snowbound Johnny ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
