po4 test says 0 but have little algae on rocks


I was wondering if zeovit additives would help? i have no more room for a reactor.
coral snow
pohls xtra
ammino acid

from the descriptions it looks like these 3 are what im looking for
can i dose these without a zeo reactor and still get desired results?
thanks for any advice
