In the first pic what is that off to the left? Do you have a bubble curten or an air stone in the tank? Thats what it looks like.
Yep its cyano
. Excess nutruents and low water movement are two main culprits of this.
My 80 gal
tank was littered with this junk soon after I added some slightly uncured live rock. The live rock was producing just enough ammonia and other nutruents to fuel the cyano
growth. Over a period of 6-8 weeks I had this UGLY growth on my tank. Then as the rock finished its curing process and was releaseing less and less nutrients the cyano
started to receed. It is now gone.
You say you feed brine. Is this frozen or live? You also say you feed frozen prepaired foods. I suspect that would be one of the sources for the phosphates.
Feeding your fish once a day will not hurt them. It sounds like you was also feeding to much. (dont feel bad this is common)
Feed sparigingly. Maybe even skipping a day here and there.
Know that in the wild the fish do not know when the next meal is so they will attack each and every meal as if its their last.
On a second note.
You can link images using the [img] tag. If you have a place on the net you can upload your images you can use this. in fact we want people to link images as much as possible as it will not use up our storage space. If you have no method of linking your image to your own web host then you can attach images like you have.
Either way thanks for the photos and trust me your tank is not LOST.
