Thanks, Tank Girl, It was to the white line, but I spilt some b4 taking the picture. It looks lime green at first. Then turns to the color that shows here. Still in the lime green family, not the moss grey family, and no blue tint at all.
I don't have another sample b/c I just did a 50% WC and cleaned the brown algae off everything. It's less and less with each cleaning and I added phosguard today. I'm only going to leave it in for 36hrs or there abouts.
