when i first started I did everything half rear-ended. I used tap water never checked for ph or calcium or any levels other than ammonia, salinity, and nitrate. Now Recently I decided im gonna give it a real go. Bought a ph tester(battery operated). Bought test kits for alkalinity, calcium, phosphate, nitrate. I am now using ro water. I have done 4 water changes with ro water. DOing 10percent water changes a week. Not sure what my ph was in the past. lol, now its up to 7.8 or so. I am using kent marine buffer, but 4 days later i have only seen ph go up .3-4 or so. I added buffer a few days ago but now i stopped to see where everything is at. I wanna have coralline spreading. could never get it to spread. I have red and green algae on rocks. Not cyano though. I have coralline in tank but it never spreads. any ideas
