Will it work in a sock in the sump or do I HAVE to use it in a reactor?Rowasphos or PhosBan
Buy the reactor. Best $35 you'll ever spend. Plenty of vendors around here can get it for you. I'd go with Phosar HC. IMO, slightly better and slightly longer lasting than the others and works out to be the same price when you consider the amounts used. Don't over do it. You'll strip your tank and stress out and bleach your coral.
