Rock came from an established tank, and has been in spare tank for a couple of months. Sand will be brand new caribsea Fiji pink.
Once tank is settled I will be moving zoa's out of
RSM 130D.

On Another tangent might as well ask it here. I had fairly high phosphate in my existing tank. Upwards of 4ppm (Hanna meter) so I started running rowaphos to bring phosphate down. All of a sudden after bringing levels down I had an outbreak of green algae, never had a spec of it for almost a year. But was worried high phosphate was making zoa's unhappy. Phosphates were brought down to 0.02 over a couple of weeks, any insight as to why I had the algae outbreak?

if its a new setup i would wait until the first fish foods are added before starting. other than that youll be fineas c/n and p are limiting factors in bacterial growth.i

ts hard to say as for the algae , algae also uses nitrates as well and other things including iron.

bryopsisi has been know to do quite well in low po4 envioroments as well some other macro algaes.


not sure why at 4ppm you werent getting algae but i have known plenty of tanks with high po4 and no algae issues , the consensus is that is if algae isnt an issue then po4 isnt a huge concern that needs to be fixed overnight. in fact if po4 becomes too limiting then corals begin to suffer.

sudden drops or rises however in po4 tend to cause harm to hard corals and even zoanthids.
