No, you do not have to change the water but you do need to wait until the CL reading is 0 before adding Baquacil or there will be a reaction and the water will turn green.
Go to the site link bellow for a guide to converting from baquacil to chlorine. Keep in mind that if you have a sand filter you will have to also change the sand in it as it will harbor traces of baquacil.
3 months...its not worth it! It should take only 2 or 3 days to treat chemically. Or you can dump the pool and refill, making sure to rid the filter of all baquacil mess as well (change cartridge, or change sand etc). e-mail me and I can send instructions re how to convert off baquacil.
Baquacil and Chlorine are not compatible and if added will turn the water green and throw off all of the other readings. The product that can be used to fix this is called Baquacil Chlorine Neutralizer. You also have to change the sand in your pump, or it will gum up
If you read the directions from baquacil you will find that yes you can indeed change from baquacil to chlorine. It is extremely important that you use up all the baquacil product and eliminate it from your pool prior to adding the chlorine. I have successful changed over two different systems and chlorine is much less expensive.
I would like to convert to chlorine. Can you post the instuctions here? Wait for what? As soon as you have made your mind up to change, just do it. The baquacil won't go away on its own. Nor will the slime and gunk it leaves in your filter. For instructions as to how to convert from baqucil to chlorine, or saline system - e-mail me and I will send by attachment.
To change combined chlorine to free available chlorine, you can perform a shock treatment by adding a chlorine shock product to the pool water. This will help break down the combined chlorine compounds and convert them back into free available chlorine. Make sure to follow the product instructions carefully and retest the water after treatment to ensure proper chlorine levels.
Chlorine can change from a gas to a liquid or solid under specific conditions. At room temperature and pressure, chlorine is a gas. By reducing the temperature or increasing the pressure, chlorine can be condensed into a liquid. At very low temperatures, chlorine can solidify into a crystalline form.

Make sure that you change all filters when you make the transistion. If you are using a sand filter make sure that you change the sand in it. If you don't you will have a m-ess that looks like foam from the sea. I have done this and I know...this happened to me... You have to make sure that you get all of the non chlorine product out of all of the filtering aspects.
That is not an easy answer but here goes! Baqualcil is not compatible with chlorine in any way shape or form so the best thing to do if you biguinide level is above 30ppm is to ride it down let if go until the level is 30ppm or lower. Take you pool water to a pool store and have it professionally analyzed. Once you are at that point you want to shock the pool with 3 pounds of monopersulfate per 10,000 gallons of pool water 3 days in a row. Then have the water check again at the pool store to make sure your level is below 10ppm. Once this is done add 3 pounds of calcium hypochlorite per 10,000 gallons of pool water. Make sure the shock is at least 65% available chlorine or higher. The pool will turn green do no panic! Next, if you have a sand filter, change the sand in the filter. If you have a DE filter use a chemical cleaner that is designed to clean biquinide filters, if you have a cartridge filter do the same as a DE filter. Now it is time to start using chlorine tablets. Keep in mind that every time you shock the pool for the next 2-3 times the pool will turn a light green then go to blue overnight this will slow go away over time.
chemical
Reacting violently with chlorine is a chemical property because it describes how a substance undergoes a chemical change when coming in contact with another substance, in this case, chlorine.
