Hi all.. been battling low ph in my tank for a while.. use a ca reactor.. stays around 7.6 or so.. tried using outside air on the skimmer... aeriating the surface water.. etc.. was thinking of getting a Kalk reactor and hooking it to my controller.. and based on ph having it dose.. first can this be done?? Second I was thinking of using a apex dos to dose.. can this be done?? Thanks
