How can I fix my alkalinity? I have my dos pumping 15 ml a day in the sump, that's with my trident set to automatically dos if levels go below 785. My alkalinity keeps going down though. Right now it's 7.41. I am dealing with a bubble algae problem right now, so idk if that is making alk dip. All my other parameters are good, so I don't want to just add more alk if it's going to throw the rest off.
