What is pH and why is it so important to my garden pond and spa?
pH is a measure of the concentration of dissolved hydrogen ions in water. When a hydrogen atom loses an electron and becomes a hydrogen ion—a proton—it can dissolve nicely in water. Actually, this proton sticks itself to the oxygen atom of a water molecule, producing a hydronium ion (H3O+) that is then carried around by shells of water molecules. The higher the concentration of hydrogen (or hydronium) ions in water, the lower the water's pH. More specifically, pH is negative the log (base 10) of the molar hydrogen ion concentration. That means that water with a pH of 6 has ten times as many hydrogen ions per liter as water with a pH of 7. Pure water naturally contains some hydrogen ions, formed by water molecules that have spontaneously dissociated into hydrogen ions (H+) and hydroxide ions (OH-). Pure water has enough of these hydrogen ions in it to give it a pH of 7. But if you dissolve acidic materials in the water, materials that tend to produce hydrogen ions, the pH of the water will drop. If you dissolve basic materials in the water, materials that tend to bind with hydrogen ions and reduce their concentration, the pH of the water will rise. Water with too many or too few hydrogen ions tends to be chemically aggressive and we do best in water that has a pH near 7.

Suzuki Bandit 600
In any objective test between the machines on this list, the Bandit 600 would probably come near the bottom. Its slower than most of them. It wont handle as well as any of the sports bikes. It cant even really offer the same practicality, thanks to the lack of fairing. But when we look back in decades to come, the Bandit is one of the few machines that can truly claim to have spawned enough imitators that a class would be named after it ? for a long while, any naked, standard bike couldnt avoid being called a Banditrival. And then theres the sheer breadth of its appeal. Sensible, hivisjacketed, greyhaired riders loved them. But so did newbies. And then there were the camotrousered, Simpsonhelmeted wheelie fans that were nothing without their Renthalbarred Bandits. Surely the Bandit name, and such a versatile bike, is overdue a comeback?
