Thanks for the replys, I bought Rendezvous delux spa care kit. It contains Ph up , Ph down, 50 GLB test strips, brominating disinfect tablets, protect plus (protects against stain,scale and rust),activate (shock treatment without clorine to clear water eliminate odors),spa clarifier (clears cloudy water and improves filter efficency),foam out, natural clear(naturally clears cloudy water and eliminates scum buildup)and finally a bromine tablet float. WOW seems like a lot of chemicals. Do you think I will need them all? Thanks fellow tubbers for the imput. My Tub
