FWD for Pinched Mantle...

[E-A-G-L-E-S]

My 5" crocea definitely is showing PM, it states to do a 20-30 minute FWD at the same PH and Temp. of tank.....how can i raise the PH of RO/DI water safely to do this?

baking soda or the ALK portion of a 2 part.

Remember that is take very little to change the pH of RO due to it having no buffers in it.
