wow thanks for the responses. well my question now is, from now does it get better,worse,same, this whole situation is new to me but not new to the hobby. I have had the tank for almost 4 yrsnow. i can remeber of only 2 small ick outbreak, never anything major. Like I said have a powder blue,yellow tang,hippo tang, 3ft zebra eel,wolf green eel and a bird wrasse in a 144 semi circle tank.Had a emperor angel for 21/2 yrs until this problem that he got velvet and i couldnt save. thats when i paniced and had to do the emergency copper. Live rock was taken out before medicating. So now y do i have 2 take out live sand?
