Chemicals and water top up

[tpirovol]

Hi Everyone,

I need to top up my water in a few days, do I top up now and add the chemicals, do add chemicals now and top up in a few days or does it not matter?

My PH is at 7.8 so I need to add MA.

Thanks T

Add water, mix then test to see what you need to do to it.
I wouldn’t add MA yet. 7.8 is fine and wait to see what fill water does, unless you know fill is high ph or TA.
