Algimycin Yellow is sodium bromide. This means you now have a partially bromine pool, and will loose chlorine VERY rapidly when the sun is out, probably for the next month. Using sodium bromide is a 'trick' to overcome the high stabilizer. A better trick is simply to raise chlorine levels.

But, it's too late for that: unfortunately, you've already been "pool-stored". So . . .

1. STOP buying and using goop. No blended chlorines. If you use cal hypo, make SURE it has a chlorine content of 65% or higher. Otherwise, do not buy it.

2. Purchase and use a cheap OTO / phenol red test kit (yellow / red drops).

3. Begin treating your pool with 1 gallon of PLAIN Walmart bleach each evening -- that's about 7 ppm of chlorine. Skip the next dose, ONLY if the OTO test shows a dark yellow result in the evening. On the 3rd dose, brush and vacuum your pool.

4. Continue treating the pool this way for at least 1 week after all sign of algae is gone. If you do not see distinct improvement after 3 doses, go to 2 gallon doses.

5. You *CAN* swim in the pool, so long as the OTO does not give an orange result.

6. Once the algae is gone, you can drop back to 1/2 to 1/4 gallon of bleach each evening. BUT, because of the bromide, you will need to be sure to add SOME chlorine each day. After a month of sunny days, the bromide may be gone (converted to bromate), but ONLY if you have been chlorinating consistently. Once the bromide is gone, chlorine consumption will drop off.

7. Read the Best Guess page, linked in my signature. Because of the bromine, that page will not apply immediately. But once you see the chlorine lasting through a sunny day, it DOES apply, and you must follow the dosing on that page, to avoid a recurrence of the algae.

Good luck!
