Floating slime/ algae following treatment

[PoolDoc]

OK. Had some errands to run.

So first steps:

1. Get a cheap OTO/phenol red test kit (yellow + red drops) and test BOTH pH and chlorine. Report the results. If the chlorine is above 3.0, report the COLOR the OTO turns (dark yellow, orange, brown).
2. If the phenol red turns a weird color not on the tester, then you do NOT know what the pH is. Just to be safe: add 1 box of PLAIN 20 Mule Team Borax per 10,000 gallons . . . SLOWLY to the SKIMMER, with the pump RUNNING and the water CIRCULATING. high pH won't damage your pool; low pH will. Also, high pH is better when you've got a bunch of chloramines in the pool.
3. Unless the OTO turns dark orange or brown, add 1 gallon of PLAIN 8% bleach for each 10,000 gallons of water.
4. Get a set of pool store test results that include pH, calcium, alkalinity, and especially CYA
5. Describe your pool: gallons, pool type, pump & filter type
6. Report all this info.
7. Meanwhile, once you've added bleach and borax -- if you do -- you can TRY turning the pump off at night and seeing if the 'floc' or whatever the pool store sold you will settle overnight. If you are lucky, it will
8. Prepare yourself for the long haul. Cleaning up messes like this is rarely quick and easy, especially on above-ground pools.

BUT if you have an IN-GROUND pool, do NOT even THINK about draining and refilling unless you KNOW you can do so safely. People FREQUENTLY DESTROY their pools by doing so!

Good luck!
