Some people get water like this out of the tap. One of the posters
on the cichlid list has tap water at pH 9+. Amazingly, she can keep
plecos happy at this pH.
Most people with rift lake cichlids try to keep the pH over 8. If you
have a lot of limey materials in the tank and reasonably hard water to
start with, the tank will equilibrate to about 8.2-8.4. Baking soda
will get you there too. Some purists aim higher for Lake Tanganyika
Btw, there's a tilapiine cichlid that lives at pH 10.5+ in spring outlets
running into Lake Natron in eastern Africa. Lake Natron has a pH of 11
and sodium carbonate forms a crust over much of the surface.
I think we've gotten rather far from the topic of live foods.
