Good eye. I think most of it is remnant from one of the 3 massive BBA outbreaks I fought through. Eventually, I'm going to pull the lot and re-plant the clean tips but want them to grow out more b4 I do. Probably not till I get the ADA ASA and do all of that at once. That area is however the slowest area for water movement. I may try to change things up a touch and see what happens. Maybe buy some new hoses and put my spray bar on an end so the whole tank gets circulation.
Thanks!
