Ongoing issues

[jeremyweber]

Hope someone can help me. This season has so far been a bust And I am hoping to turn it around. Replaced de filter with hayward 244s model and am using 150 lbs of zeos sand. Filter replacement is done and be up and running for about 5 days. Pool was very dark green. Added a bottle of somethIng like swamp treatment as recommended by pool store. The next morning the pool surface was covered in an icky film. It's dissipated to some extent but its still really bad. I need to retreat the pool for algae but I don't want to cause any more foaming issues.

I have tried to scoop it out with my skimmer but it's more persistent than I am at this point. Any one have any ideas?

My ph is still too low it reads 6.8. On my test kit. Chlorine is in the 3-6 range

Yeah, it's actually pretty simple.
I'm guessing that since you are using a 300# sand filter you have at least 15,000 gallons.

You need to get your pH to 7.0 at least. Start by adding 1 box of 20 Mule Team Borax and wait an hour and check pH.

I"m also guessing your CYA (stabilizer) is very low.

Your chlorine is 'way too low to clear your pool.

Start by adding 1.5 gallons of 6% bleach for every 10,000 gallons. That will raise FC (free chlorine) by about 9ppm...bringing you to between 12 and 15ppm. That will start killing algae. This is based on my knowing nothing about your pool yet.

Test your water and add bleach whenever your FC drops below 12.
Meanwhile either test for, or have a pool store test for:
FC
CC (Combined Chloramines)
TC (Total Chlorine)
pH
Alk or T/A (Total Alkalinity)
CYA (Stabilizer, Cyanuric Acid, Conditioner)
CH (Calcium Hardness)

And let us know if your pool is vinyl or hard-sided, and how big it is.

Thanks for the quick reply. Will take water sample to store tomorrow and post results. Pool is vinyl inground and about 20k gallons.

AnythIng to do about the foam issue. Or should I get the chem right first?

[CarlD]

really, the only thing we'll have you address at first is chlorination and pH. Everything else can wait but we need to know what they are. Heavy chlorination should take care of the foaming, too.

Do yourself a favor and buy a good test kit so you don't have to rely on the pool store. We recommend the Taylor K-2006 or 2006C. If you order it through the Amazon link in my signature, the Pool Forum makes a little money which helps keep this forum up and running. (Only buy from Amato Industries, however. Some of the other sellers through Amazon are substituting the K-2005 which you do NOT want.)

Carl I have put at least. 4 gallons of 12% chlorine since saturday so I bet its the cya. Will get results tomorrow and post.

Watermom looking at the test kit now. What the difference between the two? And I don't see it available from amato
