Biguanide Products

I used Biguanide products in my pool the first year (2007) and pool was clear all summer. Last year (2008), I used it again and had green sides and floating white stuff in water most of the summer. I Could not even see bottom of pool. I used so much Biguanide sanitizer, algesides, and flock and nothing seemed to help. I live in Southern Illinois. Is this a bad idea to use these products in an above ground pool in Southern Illinois. If so, what do you suggest I use? My pool is 24 round, 52 deep.



Hi. My pool chemistry is very basic. I use chlorine tablets in a floating chlorinator and I use vinyl shock treatment every month. During the hotter months I shock twice a month. I always keep granule chlorine on hand for a fast boost when needed. If I check the chlorine and if it's low I add granule chlorine and refill the chlorinator with tablets. The tablets take a lot longer to raise the chlorine level when that is needed.

That's all I do and I always have clear water. One thing I attribute that to is the way I run the filter. The warmer the whether is the more hours a day I run the filter. Any time I see any sign at all of the water not being clear I run the filter nonstop until the water is clear again. That is something many people do not do when they start having water problems.

It might also be a good idea to take a water sample to several different pools stores and see what they suggest. I would visit several stores because they are all in the business of selling chemicals and it is amazing what some stores recommend to clear up your pool. Especially when all that was really needed was shock treatment and running the filter nonstop.

Check with neighbors and friends also. See what they are doing to keep their pools clean.
