I recently dumped my Acid Neutralizer tank and replaced the bed and media due to a low flow issue and also it hadn't been done in atleast 10 years.
My raw PH is 5.5 so I used a 75/25 blend of Calcite/Corosex which is about what I have been adding annually . Maybe 10% more Corosex this time because I had trouble getting the PH above 6.8 previously. Now the PH is in the 11-12 range?? My Oakton meter is calibrated and still shows a raw PH of 5.5 so I assume it's correct. I'm stumped if anyone can help please.
I'm contemplating dumping it again but don't know what ratio to use or if I should just use straight Calcite.
