Hi I’m new here but I’ve been keeping a reef for a year now and everything has been going great except for the fact that my ph stays low and my alkalinity is through the roof. I’m not sure what’s causing my dkh to keep climbing. I do a 25% water change every other week. I’m not dosing A&B because my calcium stays pretty steady at 420 ppm or so but I do add seachem reef complete when calcium gets low and seachem reef buffer to raise my ph. I tested dkh this morning and it took me 30 drops to get the color to change from blue to yellow with the api test. If anyone wants to help me it would be greatly appreciated! My name is Eric and I live in the eastern panhandle of West Virginia. Thanks in advance!
