Have you done hypo on tangs? Any side effects?
Yes, I treated my Yellow Tang with hypo and she did fine, in fact no ill effects at all. Not to be reduntant but watch that PH
because it will take a dive with each FW
water change you do. Have some buffer standing by at all times. I do suggest buffering the change water so the PH
roller coaster will be a lessened.
Definately in qt
, your inverts couldn't handle the drop in SPG and the polyfilter is fine.
Do you own a refractometer? it is needed. I would also (if you can swing it) get a PH
monitor, it will make life easier on you.
To get the water to treatment level do 2 (20% of the water volume)changes a day 12 hours apart until you get there. Should be there in 3-4 changes.
All the fish are in qt
...right? I know, its a pain..
Good luck and keep us posted.
