Crystal Clear water, but.......

[Earl J]

There's always a white/green/yellow residue trapped mainly in seams of 16x32 IG.....I assumed it was algae...But no matter what I do, it returns....can u help?

Could it just be pollen? Debris always tend to settle near seams in pools. In my pool, that is where I always tend to have dirt. It gets stirred up in the suspension of the water when we are in the pool but when the water quiets back down, it resettles back to the floor along the seams.

What kind of test kit do you have? Can you post some current readings?

===========================
It might be pollen..I just wanna get rid of it...The latest readings were just fine...6/8/14
But here they are:
Total Clor: 2.9.........Free Clor: 1.1.......Total Alk: 170........Calcium Hard: 150; but I added since then......Stabilizer: 65; but added more.......(readings came from local pool store)....I'm using reg test strips: which don't give readings......only colors....QUESTION... Why would pollen not stay in filter until "backwash" ???.......Thx

Actually, if your readings are accurate, and honestly, pool stores aren't know for their accuracy, your numbers are not fine.

FC + CC = TC So, that means you have a CC reading of 1.8 which would not be good. (You want CC to be 0 or at least no higher than 0.5.)

Therefore, unfortunately, it may very well be algae.

With a CYA (stabilizer) level of 65, you have to keep your FC between 5-10 ALL the time. If it dips too low, then algae can get started. At this point, you need to shock your pool. Again, the shock level is based on your CYA reading and will be 20ppm. More about the CYA/Chlorine connection can be found here: http://pool9.net/cl-cya/

You are going to need a Taylor K2006 kit. Since it is going to be necessary for you to run chlorine readings as high as mentioned above, you need a kit that can measure higher than 5 which is the limit on these other kits. This kit won't be available locally but you can get one through this link: http://pool9.net/tk/

In the meantime, can you go to Walmart and see if they have the HTH 6-Way drops-based kit (not test strips). If not, at least pick up a cheap OTO/Phenol Red kit (yellow and red drops). Also, get a bunch of jugs of their generic 8.25% bleach.

Test and post your numbers and tell us which kit you bought and also what your volume is. Then someone here will help you go from there.

Watermom, I just ordered Taylor OTO...I already have 8.25 bleach....When u say Shock; how many 1lb bags? Also, how much bleach do u normally use? thx

[Watermom]

"Shock" is a verb, not a noun. It just means to raise the chlorine level. You can just use bleach to shock with. No need to buy a separate product.

How much bleach to use depends on your volume. Here is a link to a bleach calculator that may be helpful. It actually has other calculators as well in the drop down menu in the upper left corner. http://pool9.net/bleach-calc/

Also, what kit did you order? Only an OTO and not the K2006?
