Yes, definitely in part to the defective fish
I had a bit of HA come in on some zoos and it really likes my tank. I can kill off terrestrial plants pretty darned quickly but not the same for the underwater ones. I've been doing regular water changes but haven't really seen much for results. It was kind of a strange thing the green algaes. As soon as I kicked the browns out of there the greens were a go to take over. Less competition I guess. And then an absolute explosion of grape caulerpa that I can't seem to keep up with. Within about 2-3 weeks of the browns gone the caulerpa was insane and still is. I'm pretty much beyond adding any more "herbivorous" fish at this point. I'm thinking maybe a tuxedo urchin and some emerald crabs or something.
Its scary but I kind of enjoyed pulling caulerpa and HA the other night. I think things would get boring if I couldn't mess around with my tank occasionally
