I have stayed away from SPS for the last several years.
After fighting the red bug/AEFW wars for many, many months I felt the best course of action was to remove all SPS and let all the nasties die off.
Just keeping zo's, ricordias and fish...my ca/alk supplementation has been nothing more than 175 gallon NSW water changes for a few years.
I have just started getting back into SPS, examining every piece carefully.
Anything sketchy, sadly, I euthanize.
I have the dosers and balling salts and will begin to implement them next week.
Thank you for the replies,
Sean
