You can wait until Fall and drain some water off, which would dilute the amount of Baquacil, which may speed the process up a day or so. However, for the amount of $$$ you will save, and the CLARITY of your water, I would suggest changing now. Look at around the last page of this thread and look at my pictures of my conversion. Look at the last couple after the conversion. I can see my bottom drain plain as day now, almost like looking through glass. On Baquacil, when it wasn't scattered-smothered-covered in algae, then the water had the hazy, milky look you mentioned. It's your pool and ultimately your decision. I'm just giving my unbiased opinion as someone that's been there/done that, and I would say switch now. You will have the cleanest, clearest pool for a great 4th of July party! Plus, the $$$ you save from chemicals will buy some nice healthy t-bones for the grill.
