Here is a look at some of the symptoms hammertoe can cause. During the initial stages, you may be able to manually straighten your toe. This is called a flexible hammertoe. But as time passes, the toe will not move as easily and will continue to look like a hammer. Pressure and irritation over the joint can cause a blister to develop and become a corn over time.
Algae blooms however, can raise the pH of your pool water. The process of photosynthesis can produce enough oxygen in the water to raise your pool pH levels, particularly if tested near the end of a warm, sunny day. High pool alkalinity levels will make it hard to adjust your pH level. To lower your total alkalinity, use pH decreaser. In most cases, additional treatments will be necessary if you need to lower alkalinity more than 30 or 40 ppm.
What happens when an acid is added to an alkali? 1  the uses of acids and alkalis in a range of everyday situations, eg hair and skin care, treatment of stings and bites, treatment of indigestion, food preservation, treatment of soil. 2  how living things use acids, eg ants, nettles, humans in digestion. classify acids and alkalis as chemicals with distinct properties and uses. 2  use indicators to classify solutions as acidic, alkaline or neutral. 3  use the pH scale to compare the acidity and alkalinity of different solutions. 4  begin to explore neutralisation i.e. the reaction between an acid and an alkali.
