My HYDROPOOL SERENITY 6000 was hooked up sat. evening. my electrical guy had to take the 60 amo gfci back and exchahange it for a 50 amp. the 60 had no neutral to hook up and it was needed apparently.hopefully the 50 will be ok. maybe steve can comment on this. other than that problem we had a blast all day sunday in and out from 1 to 5 people at a time. hydro was used that day for sure.in between soaks I put the covermate together and installed the lockable clips etc... now I have to figure out the chemicals. so much to do between soaks. life is good. a full review will follow shortly.
