We just installed a Blue Hawaiian Fiberglass pool. We live in Northwest Ohio. Looked at a few different companies and settled on a dealer that was close to us and seemed to do some good work. I can say that Blue Hawaaian has a great pool but we had some minor problems. The dealer we went through gave us a great deal on an "in stock" pool but it took about a month to get it up here, and the local dealer ended up having to drive out and haul it up because Blue Hawaaian was not going to ship it in the time we needed it. The only other issue was that we wanted two cascade waterfalls installed, but Blue Hawaiian didn't do it (Vikign does). You can still have the cascades installed but that takes extra time and cost. Our local dealer ended up giving us a few "deck jets" instead, and is also supposed to be giving us a deck fountain. I can also tell you the "galaxy blue" gelcoat is an awesome way to go. It really hides the dirt and looks great.
The only other issue that we've run into has been the timing. The local dealer is high on quality, so everything we have got has been done really well. The pool install has taken about 6 weeks, which was much longer than the original 1-2 week estimate we were given. Also, the concrete work with our dealer has been exceptional.
If you have any questions, let me know, it's a big decision. I'd be glad to let you know who we went through and some of the items we had to deal with in more detail.
