The BBA just came out of nowhere one day. I've just stopped all the ferts and that's helped heaps! I take off some leaves when it gets real bad but I'd imagine it'll be gone in a few weeks.
Cardinals are the only tetra in the tank. Apart from that there's lots of plecos, cories, a whiptail and 2 T bars.
The crypts on the RHS are in some serious need of selling! lol. I've been slowly making the substrate in the tank sand, so the RHS is the only part of the tank that is left to rip apart.
