I've been using the rowa phos and my phos is reading 0.06 and slowly coming down but I noticed on my Hanna checker my alk is at 6.5 now it was at 8.5 6 days ago anyone know if the rowa is what lowering my alk? I'm dosing part a and part b 25 ml a day and am heavily stocked with sps so my question is how'd it get that low and how do I get it back up?
