ok i dont know how much pounds of lr i have because i got a dry piece of lr from a beach, but its like 20 pounds. and maybe about 5 pounds of other lr. 30 pounds of sand.
Then my lighting is just 1 bulb with a power glow lamp.
i have that 1 ph in the pic and 205 fluval filter. I did have chemipure, but i dont think it is doing anything. I have a visi-jet protein skimmer that seems not to be effective.
WHat else do u need to know?
Get a phosphate kit or get it tested at lfs. Very dangerous putting that rock in from the beach. Ya never know what pollutants might be in it. It's possible that your light could be causing or aiding in the spread of the cyanobacteria. Try reducing the amount of time you have your light on. You should get another powerhead or two. Really increasing your flow will do wonders. Continue with the small water changes and manually siphoning it out of your tank. It's going to take some time, perhaps weeks, but you can get it under control. From the looks of your pictures it looks like you may also have some calcium carbonate precipitation on your powerhead. Check your alk, cal, and mag to make sure they are in the right range. Lastly, chemipure is some good stuff and really helps improve the water clarity. If it isn't doing anything, chuck it or replace it.
