Pre-water-change nitrate measured between 20–40 ppm, closer to 20. Removed the poly-fil from the refugium chamber and added a piece of coarse sponge media to the return pump chamber to help reduce byproducts entering the pump area.
Performed ~75% display and ~90% sump water change. Dosed a general cap of Seachem Excel and completed the final spot dose on the area targeted all week — now fully BBA-free. Only small isolated spots remain elsewhere in the tank. Added Stability to help seed beneficial bacteria onto the new filter media.
