- Hi I am Jewels, I joined this group looking for some help. I have had
tanks for probably 35 years. Recently realized that the Ph in my 29
gal fresh water was about 8.3. Put in a buffer which did not lower it
at all. Had several old fish but new fish lasted only a week or so.
Have moved the old fish and started trying to find the problem. I have
about 20 lb of slate and 3 biowheel filters and gravel. Am working
through possibilities, have removed all slate refilled with water and
left the filters running, ph went back up, drained tank clean filters
and turned them off. Filled about 1/4 water and Ph is high again.
Must be the gravel. Anyone had a similar problem? Ideas
Sorry for the long post, have tried several forums with no answer.
