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.



A steady consistent 7.8 is preferable to bouncing it all around trying to
change it.
Most all fish can acclimate to a pH in this range- I wouldn't fight it.
If you must have a lower pH then reverse osmosis is the answer.
