Dosing PO4 in auto top off?

[Rcollick]

I’m going on vacation next month for a week. I know how much I need to dose a day to keep my phosphates detectable. Can I add the phosphates to my ato and do I need to keep a powerhead in there to mix it?

I think you could add it to ato and no worries about adding a pump

 

[Randy Holmes-Farley]

Yes, assuming you add nothing else, it’s ok and no pump needed.

I hope he doesn't come back to PO4 of 5.
