I have been using baquacil / soft-swim products for many years. The only main issue I've run across is white water mold. The newer products in the Baquacil line seem much better than years back. Also, I think a key is to keep a regular maintenance schedule - using oxidizer every week and following up the additions with CDX - a relatively new product that came along only a few years ago. If things stay as they are now, I have no plans to convert back to chlorine. I got totally fed up with running into a chlorine demand situation that finally called for like 100 lbs. A friend of mine converted to Baquacil for the same reason. I do think that you need to be willing to work with the filter a bit more with the biguanide systems than with chlorine since it does seem to sometimes necessitate more frequent filter cleanings due to pressure increase, although I've noticed that has improved as well with my new plaster. I have no doubt that Baquacil is a more expensive system, but I'm fine with that if it works for me. I did not care for working with chlorine and especially hate swimming in those hotel pools where the chloramines are all out of whack and you practically gag before even getting in the water.
