I know I said I would leave the ph alone...

The LFS said start right junglre might might help but i am skeptical. Does anyone how hard of water Jack dempsey and green terror can handle
 
could you send me some info or links on ROs and other methods of softing.


some good info scroll down to the pH and water hardness stuff. Should help.

i believe you are running into your high hardness buffering your pH to change (essentially blocking your hard work). If you can make the water soft and lower your pH, and then raise you hardness back up a bit - you should be good. Careful with any fish though.
 
thanks
