I would change that to 30% every 3 weeks or 10% a week. That could bottom your nutrients out.My nitrates are sub 5 and I do 30% weekly WCs. I’ll test po4 and see. I don’t have gfo or any po4 reducing media to bottom out anything.
My WC schedule was based on "the solution to pollution is dilution". IIRC 30% a week is approximately 90% per month. I'll try only changing 5-10g per week.I would change that to 30% every 3 weeks or 10% a week. That could bottom your nutrients out.

The solution to pollution is dilution, but stripping your nutrients out can cause bad times. Dinoflagellates is one example, where it's pretty common to have undetectable/limited phosphates as a precipitating factor for a bloom.My WC schedule was based on "the solution to pollution is dilution".
