Hi I'm finding suddenly am issue with firstly their brown algae over everything that plastic egg crate for example was new few days or so ago and now got brown algae already on it also my zoas have gotten covered in algae and also green hair algae. what treatments can I use for this and will this kill my zoas? Also anything that will eat that algae without harming it. in the last pic that zoa is covered now in green algae I've had it weeks amd it has still never opened either is it now dead??
