The following foods: Milk, butter, margarine, real cheese, plain yogurt, most ice cream without gluten-containing add-ins. Vegetable oils, including canola. Plain fruits, vegetables (fresh, frozen and canned), meat, seafood, potatoes, eggs, nuts, nut butters, beans and legumes.
Alkalinity Balance, pH up, pH down, Calcium Balance, Water Stabilizer, and clarifier are all swim-safe chemicals. Wait about 20 minutes, and you are free to swim. We suggest adding algaecide, Super Erace, and shock at night, after everyone is out of the pool. It is safe to swim again the next day.
The best time to shock your pool is during the evening, when it is not in use, so the chlorine can be applied without interference. For faster treatments and a quick chlorine boost, you can use Shock Quick 10 [text link to product page] at any time of day and you can use the pool just 15 minutes after applying.
