Any idea people

Any idea guys what the red stuff is it seems to be coming off the green zoas

 

Red cyano bacteria. Not coming from the zoas. Check you nitrates, phosphates. There's so many reasons why this stuff comes along. New tank, high nutrients, to much light......list goes on. Look on here in previous threads in how to combat it. It's a pain.

 

I said it was the zoa coz i moved it from the patch at the back now its started at the front of the pic

 

dsc is right, it's cyano there is a lot of information on this forum in terms of getting rid of it. It just was coincidence that it popped up like it did

 

Could it off been introduced with the new corals though?

 

Possible but it could have been dormant from any other addition to your tank; rock, sand, coral.

 

The cyano will usually form where the nutrients are. The rocks/sand adsorb these nutrients.The nutrients will come out of the rock/sand slowly over time.The best way to combat it is through steady,routine maintenance.Chemical filtration and an increase in wc's will eventually win but you have to be consistent for quite some time to see results.
