I have a 6 year old in ground pool that my local pool supply store started treating with Baquacil from the beginning, so that's all we used. It generally takes about 3 weeks to get the pool clear each spring, sometimes gets cloudy again mid-year, the product is relatively expensive and my shock readings never seem to be where they are supposed to be. I would love to convert to something else, but I have two major concerns that I really need to 'sell' to the rest of my family before doing so.
I have three females that use lots of blonde hair coloring living in my house and using the pool. The original pool store owner has absolutely convinced them that they are going to end up with green hair if they used chlorine or another treatment method. Quite frankly, if I convert the pool and someone ends up with green hair, you will be finding me at the bottom of the pool, so I need some assurance that won't happen.
Secondly, due to my work schedule, the pool generally can't get any attention during the week. 100% of the pool chemistry and maintenance is done by me, and the nature of my work has me gone most of every week. I generally devote Saturday mornings to getting the pool back in shape, but on those occasions where there's a weather or scheduling problem, that falls over into Sunday morning. There's just not really any way that anyone is going to do anything to the pool for 7 days most weeks, 8 days occasionally.
I perceive that while less expensive and more effective, alternatives to Baquacil are more 'needy' in terms of need to constantly monitor the chemistry levels (again, basing this on the 'knowledge' of my local pool expert). The Baquacil does seem to be able to 'hold its own' for seven or eight days until I can get back to it, and doesn't seem to be any better or worse when I get one of those rare weeks when I can fool with it more often.
Thanks in advance!
