Lots Of Algae in Pool This year

I have a Gunite pool in CT. I have had the pool for three years and this is the first year that I
had algae growing on the walls (just below the tile). I have never had this problem and have never
used any algicides.

This year its a problem.

I was wondering if others have noticed excessive aglae this year or could it be due to the fact that
this year I started using a non-chlorine shock? I always used a chlorine shock until this year.

I'm interested to hear what others have to say.

Regards.

I don't believe that the non-chlorine shocks kill algae. They supposedly burn up organic wastes, but
I don't think algae are affected.

Other things you might also check:

1. Stabilizer level. If it gets too high, your regular chlorine will become less effective.

2. Phosphate levels. These compounds are not burned up by normal chlorination or super-chlorination,
but there are specific products which remove them.

I've never used algecides. I don't think they are necessary if everything else is right.

There ain't nothing better than scrubbing the walls,flaws, and a massive dosage of chlorine. Keep
your filter clean. You don't need agecide, just more chlorine.

We've had a very wet spring and summer. When brushing, an often over looked area is behind the under
water light's rim, the bottom last spa step, and behind the thru-the-wall skimmer. Dead algae
encapsulates and protects new algae, so a good brushing is needed. Use rope to get behind the water
light rim and work the rope back and forth. Non-chlorine shock is a very strong oxidizer but a good
chlorine residual is needed too. Chlorine can be thought of as a poison to algae and bacteria. If
you had a ozone generator the ozone would actually infiltrate the nucleus and destroy the membrane.
Something to think about. You didn't ask but here's something else to consider. Ozone and chlorine
can eliminate e coli. much faster than chlorine alone. I don't want to sound gross but reality is
kids and maybe some adults aren't very clean down there.

Hello,

Another thing to consider is a product called Phos Free by Natural Chemistry. This chemical removes
phosphates (which is the food for algae) from your water.

You can find more info here

They have been good to me and are quite helpful with pool problems
