whats causing the bryopsis?

would say started with neglecting water changes but even though getting back on the tank, since the stuff is established it's hard to get rid of.

guess my point is, unless you figure out what it is that is causing your flare ups you will likely be having an on going war with the bryopsis....raising your Mg will work to help get rid of it , but having your Mg that high throws your water chemistry way out of balance..... you should try and think about what is at the "root" of the problem:wink:......
