[Swim Spa Recommendations]

I have 14 foot swim spa with 2 seats on opposite ends of swim jets.  The seats have plenty of their own jets.  I keep water at 94 degrees which is not too hot for swimming  and warm enough to get it to 100 by evening.  The all in one model works for us. My electric bill went up about $100 a month.

[Bubbles Or Blisters Fiberglass Spas]

I have a spa that is 4 months old.  Tiny blisters are developing in the seats and a couple of the walls look like the shell is wrinkled.  The fiberglass lining shell is the white marble finish.  Is this repairable or should I request the manufacturer to replace the whole unit?
