water change query

[fatfei]

Hi I have a tap water of 8.2 Ph but due to running a co2 unit for my plants the aquarium water has a much lower Ph of 7.4. When doing water changes even small ones like 10% will I need to add anything to my tap water to lower its high Ph so not to upset the aquarium's Ph?

Many thanks

Nope, PH changes due to CO2 will not effect fish in the least. Change away,.
