I am glad to see this comment, because it's hard to digest the message that algae issues can be resolved largely by having good CO2 levels/flow/etc - it's just not true in all cases.

On my tank, I had my CO2 running steady 24/7 with massive flow and a high enough levels to kill off some fish and all the invertebrates - a bright yellow DC! That was a clean restart of the entire tank, and included some aggressive Excel use and constant pruning etc. The BBA came back and took over the tank within a couple of months.
