Please help. My tanks calcium is very low. Checked this morning and it was 150. I know thats really bad. How do I get it up to where it needs to be. I have had a probem with low calcium from the get go but it seems to be getting worse over time. I have been adding purple up every other day and a 2 part (Kent) Tech Cb. HELP please, don't know what to do and it is really frustrating to me.
