I seem to remember that someone on this list had a great success with a snail-eating fish, could anyone let me know the name of this fish? I've just tested my water prior to setting up a new tank in a new home and have found that it has a hardness of 40F according to my (new Dupla) test kit. Unfortunately I don't know the relationship between this method of measuring hardness and degrees of kH, gH or ppm, can anyone let me know? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
