I have a 300l tank with discus etc
Aiming for a ph of 6.5.
My issue is that the tap water is very soft (which is good for discus apparently) and has PH of 7.0/7.2.
So whenever I do my weekly 25% water change I have the PH getting back to 7.0 etc.
To date I have just used "PH down" each water change and over the next day or two i get it back to approx 6.5.
Is this the only thing I can do? Manually add a PH down product?
I am also using a bit of KH buffer lately to try and keep ph more stable. So have the kh from 10 to about 20/30 now.
