EDIT 6/14/13- In light of the information received below, I have decided to not fool around with an algaecide at all.
I will continue with my liquid bleach treatment. It's been working so far and now my wife is convinced thanks to you all.
Howdy all, I need some enlightenment...
Last year, I kept the pool clear pretty much just using ye olde Clorox from Wally's, no problem. Now, we get our other pool chemicals from a small, family owned (3 generations now) pool store. They beat the heck out of the "super stores" even if their prices are a little higher. They generally don't try too hard to "push" chemicals but, on this item I am not so sure.
They want me to add some algicide (how do you spell that anyway ?!) weekly. I didn't bother with the alg- my bleach keeping things largely in check. Also, I don't think I am using overmuch bleach either, about 4.5-5 gal.s/weekly on average. I added some algae control stuff two or three times as I deemed needful is all.
I also use 'pucks' to help hold chlorine levels constant. I use either with or w/out stabilizer depending on CYA levels. (I have and use my own test kit letting the pool store run their tests for a comparison. Our test results are generally comparable.)
Now, my wife is wondering if we used the alg-howeveryouspellit-cide, could we get by with less bleach? Is that the case and if so, is it desirable? Basically, we're wondering if adding alg-cide would reduce the chlorine/bleach requirement.
Other considerations that I can think of are cost? Is it less expensive just using bleach or would the mix (assuming it worked, is desirable) be cheaper?
What about chemical exposure? Is less bleach or alg-cide preferable as to what our hides are being exposed to? (Assuming chemicals in balance.)
That's about it.
Thanks for your replies.
