Dear all,

My tank water was tested PH 7.8.
Any effective method to reduce value other than using PH down solution.
I tried changing 20% water each day, not much helps.

Thanks

assuming you need to reduce the PH for the type of fish your keeping then
you can mix the tap water with R/O water or you can filter your tap water
through peat moss. I would not recommend using chemical to alter the Ph as
this is a temporary solution only.
