I have been around these bases myself, trying various soil additives and then testing water. To this date, Florite is the only substance I have found that does the plant thing without increasing General Hardness. Yes, VERY expensive. One solution I have found is to use plant baskets on a bare bottom or black sand bottom tank. Put the Florite in the basket. Plants grow like crazy with very little investment in Florite. If concerned hide the basket with driftwood or inert rocks. john On 24-Apr-01 Al Smith wrote: > > ----- Original Message ----- > From: "mopargrrl" <mopargrrl@mindspring.com> > To: <apisto@listbox.com> > Sent: Monday, April 23, 2001 8:11 PM > Subject: Re: profile as substrate > > >> Al, >> >> I just started experimenting with Profile.
