Foam in a pool that uses Baquacil can have a leak in return hose. It can also be the result of putting too much product in the pool. You should check the chemical levels in the pool.
Yes, "Baquashock", "Baquacil Shock", and "Baquacil Shock and Oxidizer" are all synonymous. Baquacil has been changing the names through the evolution but it's the same product. Most companies are now selling it as "Oxidizer (Shock)" - http://www.backyardexpress.com/baquaspa-oxidizer-shock.html
You do not measure the Chlorine in a Baquacil pool because they are incompatible.

The only reason the pool would turn green would be if the Baquacil is not entirely out of the pool and it reacts with the Chlorine.
No

If you have Baquacil Test Strips then going to the Pool Center would not be necessary, you can just do it yourself and adjust the readings.
I try and shock my pool every other day, or, if it rains, shock it at night after it rains (never during rain).
You would be safest using Baquacil pH Increaser, which is a high purity, highly active dry alkaline product used to raise pool pH. In non-Baquacil pool water, both Soda Ash and Hydrochloric acid are used to raise pH levels. Pool shops are a good place to seek advice also.
I have been using Baquacil for 18 years in an in-ground pool. I used chlorine in an above ground pool prior. The cost difference is obvious. Starting off new, Baquacil is very expensive. As the years go on, the cost of the sanitizer drops dramatically because of the baquacil buildup in the water. You dont have the chlorine smell and the eye burning. I recommend washing the baquacil from your hair since the hair tends to get heavy after swimming. Foaming is also a problem with baquacil. I still prefer baquacil and intend to use it after I install a new liner next year.
only about an hour if you are using baquacil
