John, When I'm in Europe(once a year)I usually stock up on a peat product from Sera.It is a filter bag filled with peat granules(just like Fluval's but much cheaper)made for pond filters.I think it comes in 1l and 2l size bags. I cut the bag and use the granules in a regular filter just like any other filter material. I got that tip from a Discus farm owner in Germany. It is not messy at all and works for me to soften my water. I lower my Ph with CO 2 injection,I don't want to go to deep into that. That's more for the plant list. Hope this helps Max ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
