Your home page is killer. It's a beautiful site. I would recommend putting more verbiage on the home page, about us (include a picture of you and some history about yourself) and also the contact us page. Google doesn't rank based off pictures, etc. They do so off of verbiage. So relate the content to your page and google should give you a boost.
I'm glad the videos are helping you out! I usually put in the skimmer and make sure it's the last chemical I add, since it doesn't pass through the filter like bicarb does. You can also take a panty hose and tie it to the skimmer lid to have it slowly dissolve in the skimmer box. I'll check out your website shortly. Have a great day.
