LOL.. Reefwars.. too fast for me. 1Big,, I'll leave you to the pros... I'm still a newbie.
Half of the fun of this hobby is the learning curve. You're in the right place coming here.

if the tank is around 4yrs old i imagine the cyano is from you scrubbing the rocks of algae, stuff tends to build up after time in the rocks and that all would have been released and the algae itself then too.


if the flow is too strong in your tank then that too isnt good for softies and they will shrink up and die.

if light is to strong then they will shrivel up and melt.
