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.
In a new pool, with properly balanced water, average day outside and not covered with a solar blanket, the chlorine residual from a normal shocking will, in most instances, be down to a safe level of 3.0 or less, in about 4 hours on average after the shock. When you do shock, try to always do it at dusk.
