Baquacil can be difficult to remove from the water but its not impossible. First have your baquacil sanitizer levels tested. If they are above 30g/ml or 30ppm you can either 1. Allow the baquacil sanitizer level to naturally drop OR partially drain to dilute the sanitizer. Next you will need to lower your pH to 6.8-7.0. You will then need to add Non-Chlorine shock (Potassium Monopersulfate) at a rate of 4lbs / 10,000 gals of water. Run filter continuously for 48 hours. Test the baquacil sanitizer level. You are aiming for a level of 10ppm or below. If you have not reached that yet you must repeat the previous process with another 4lbs of Non-Chlorine shock and running your filter another 48 hours. Once you have reached your 10ppm or lower goal, you can start with the conversion process. Adjust your pH back to 7.2 - 7.6. Start shocking with liquid chlorine (Sodium Hypochlorite) (preferably in the evening). The amount to be added will vary depending on concentration. Check the directions on the box for manufacturers recommendations. Because of a likely high chlorine demand, shocking may be required for 7-10 days. Also watch for a precipitate to form. Brush the pool regularly and run filter continuously to remove. Don't allow the precipitate to settle as it may stain the pool. Once a free available chlorine residual has been formed balance the water and begin a routine chlorination schedule.
To measure chlorine in a Baquacil pool, you can use a test kit specifically designed for non-chlorine pools. These kits typically test for the sanitizer levels in Baquacil pools, such as hydrogen peroxide and peroxide-based products. Follow the instructions on the test kit to accurately measure the sanitizer levels in your Baquacil pool.
There really should not be too much of a problem when switching from CL to Baquacil. You just have to wait until the CL reading is down to zero and then start adding the products. The sun disepates the CL so quickly it should only take a couple days at most.

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.
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.

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.
Not recommended, Baquacil is a swimming pool, hydrogen peroxide (Potassium) based chemical. Baqua Spa is the recommended (Potassium) based spa chemical.

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 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.
