Hi,
i have a 70g planted tank at the moment with no discus in it yet and are running co2. My ph is currently around 6.3 and i have a 200ltr drum set up for aging water but my tap water is ph 7.4 and i plan on doing a 40% wc every 2nd day hence the ph swing. How am i going to stop this ph swing or is it going to affect my new discus in anyway from pumping the aged water directly into my tank. Advice needed
