water change and dosing

[lucasb.]

i just got into dosing 2 part daily and i was wondering if it mattered if i do a wc before or after my tank is dosed

Doesn’t matter but you should make sure your new water matches the parameters of your tank water.

It's going to depend on a few things:

1. Are you manually dosing once per day, using a dosing pump to spread it out over 24 hours, or something in between?

2. What are the parameters of your new saltwater compared to your tank water?

3. What is your daily swing in parameters?
