Ok, that's a relief. Let's redirect then.


1. Do not add water.

2. Buy 12 gallons of PLAIN 8% store brand bleach (Walmart?), 2 boxes of 20 Mule Team borax (Walmart?), and 1 gallon of plain 31% muriatic acid (Lowes, other hardware store) with NO sudsing or foaming additives. Also buy a cheapo OTO / phenol red testkit (yellow/red drops)(Walmart) and a trichlor floater (Walmart). Also, you'll need a small bag of DE powder to test / help your filter. You may not be able to get it locally, but you can get it from Amazon.

3. Test the pH levels.

4. If needed, use muriatic acid to lower the pH to ~7.0 - 7.2, to keep any remaining copper from staining. Mix the acid in a 3 - 5 gallon bucket: add 1 gallon of water, then 1/4 gallon of acid, and then 1 - 2 MORE gallons of water. Watch out for fumes; wear gloves and glasses. Once the acid is diluted, it will stop fuming. Add the acid around the pool, then rinse off any splatters with a hose. Then, take a brush on a pole, and stir the water to mix.

5. Once the pH is below 7.4, begin adding bleach, in 4 gallon doses in the EVENING. Use your acid bucket to dilute 1 gallon of bleach with 1-3 gallons of water, and pour around the pool. Once all 4 gallons have been added, mix with a brush on a pole. Wear old clothes (bleach EATS clothes and glasses).

6. Repeat evening doses, till the algae is dead. Once it is, fill the floater with trichlor and put it in the pool. Begin siphon vacuuming the pool to remove the settled algae. Add more water as needed to maintain levels.

7. One day after the last bleach dose, test chlorine and pH. Report results here.

8. Once you've siphoned as much settled algae as possible, begin refilling. Once the pool is full, turn the filter to the RECIRCULATE position and turn the pump on.

Your 16" filter is MUCH too small for that pool. Odds are the pump is too big, and capable of forcing the algae through the filter. Once this happens, it becomes much harder to remove the algae. My guess is, the algae particles get broken up into very small pieces that are hard to filter -- but I have no proof of that.

Once the pool is operating, TEST the filter, by (a) turning the pump off and switching to the FILTER position; (b) turning the pump on; (c) adding 2 - 4 cups of DE powder to the skimmer, (d) watching the pool return to see if the powder blows back into the pool. If it does, promptly return the filter to the recirculate position. If it does NOT, you are good to go. The DE powder will help capture the algae, but will make filter runs very short.

The tiny filter is the reason why you need to remove as much algae as possible, before filling the pool. Every year, we have several new PoolForum members who try to clean up algae, but force it through undersized filters, using their oversized pumps, and as a result, end up with cloudy pools for as much as 3 weeks!

9. Probably, before you get to step #8, you'll have your K2006. Report complete results once you have them. You may want to watch the testkit video series here: https://www.youtube.com/playlist?lis...99CY_BQXE1Jx6s
