I thought I could use a higher dKH fluid in order to read a higher CO2 level.... but ... point taken.

My drop checker is exactly above the BBA hot spot. Always has been.

I realize that the BBA will not dissapear on its own and that it has to be physically removed. After increasing my CO2 level I added some Excel in to my regime to kill that which was present. Each time I do a water change I siphon it off the wood and cut the leaves of the Anubias.

When I cut back from the Excel dosing I will see if the BBA slowly comes back again (as it always has).

Anyone else experience Excel interferring with pearling?
