My tank is never above 20 nitrates and phosphate is generally .05-.08 it’s not a new tank it’s at least 11 years old. I don’t do weekly water changes already I’m normally if it ain’t broke don’t fix it, it’s always worked with my tank so I would say I do water changes once a month. I do get algae on my glass quite a bit, and have sone hair algae going on but not very much. My blues run from 2pm-10pm woth the white coming on at 4-6. I also see where micro7 is good for new tanks so can I use it on my old tank?
How do I do step 5, never have done that before.
