So, our PDC tub has been used three times since it was delivered/setup. It's a 400 gal Malibu.
By the second (or third?) time we used it, I could definitely feel essentially an almost greasy coating on the tub, where it had been glossy smooth.
It's a vacation home, so we only get up there for a week or two every couple of months - with local biweekly (in theory) maintenance for the year.
I can assume that they'll barely check/add chemicals during their checks. So what will I need to do myself when we're up there?
Where's the best place to purchase a spare filter... through the manufacturer or some spa parts place?
THANKS
