Are you sure they are algae spots and not maybe metal stains that precipitated out when you shocked the pool with chlorine since that raises the pH?...

Unprotected Bathing. That's why you should always use condoms...err...I mean chlorine. :lol:

Congratulations on your clearing pool and ability to hold chlorine!

Given your 40 ppm CYA level (the CYA test is approximate, so +/- 10 ppm in...

Yes, that's Dichlor. And yes, Dichlor will add both chlorine and CYA at the same time. For every 1 ppm Free Chlorine (FC) added by Dichlor, it will...

Another option for adding CYA at the same time as chlorine and to do so quickly is to use Dichlor powder/granules as these dissolve very quickly. For...

If you are a Baquacil user, then yes...it sounds like typical Baqua-crap water mold. Switch to chlorine and watch your problems disappear.

BUT you...

Cyanuric Acid - 8lbs for $29.99.

Adjust pH to 7.2-7.6 (use Borax to raise pH)

Have your TA between 80-120 (use Baking Soda to raise TA)

and Superchlorinate with Bleach. (Clorox or...

Agree 100% with above...learn the religion of BBB.

But first...BUY a good test kit and dump the strips..they are notoriously inaccurate. Your pool...

This is called water mold or tissue mold and all baqu-junk pools get it eventually. The baquacil forums are filled with this exact problem.

You...

The levels for chlorine are high as we have been super chlorinating it to avoid visible algae. We have also tried to put in algaecide, but nothing...

Shock levels should be 15ppm and above and need to stay at that level over night into morning to adequately kill an algae bloom.

Hope this helps....

I think I might be paying the price for buying some cheap claifier at Lowes the other day. After putting it in the pool, I had algae within about 3-4...

If the dot never disappears, then you don't have enough CYA. There should be markings on the side of the tube. If the tube is full and you can still...

Can I rid my pool of algae using chlorine only? Or is an algaecide necessary? The pool stores always want to sell you much more than you really...

Man you must live in a perfect world. I wish the pools I take care of had only 50 CYA.

I'm sure your clients wish that too. ;)

Hey...at least...

Okay...I did a gallon of bleach yesterday morning and the fc shot up really well. Of course, the sun was out all day yesterday so it was short lived,...

ok i bought a test kit, now i have had the PH at 7.6 and the CL at 3.0 for two days and the green is gone but my Alkilinity is above 200ppm, and the...
