I successfully SLAMmed my pool after opening it in late May to a green algae swamp. Since then, the pool chemistry has been stable using BBB until earlier this week. The PH was down to 7.2 so I used pool math and added 20 Mule to raise PH to 7.5. The water is clear, but now it has a "laundry" smell, like baking soda, especially in the shallow end.
I do usually add bleach and in this case, the borax, in the shallow end. We have jets on both sides of the steps, and I pour the chemicals in that location so that it gets dispersed quickly.
One more thing- I have a Bromine pool, but I use Bleach to kick up the bromine. I test every morning, the bromine level is usually 2.5-3.5, and I add bleach to kick it up to 4-4.5. Sadly, the pool doesn't get a lot of use, it's just me, my husband, and our 4 year old son most days.
Any ideas on what could be causing the odor? My husband leaves the pool chemistry up to me, but he is skeptical about my jugs of bleach, bag of baking soda, and boxes of Mule 20. He thinks I messing up the pool somehow. I'd hate to prove him right in this case.
