(Posted with and Breefcase's permission from works written in The pressure inside a closed cylinder containing a volatile non-polar liquid like CO2 is determined solely by the characteristic VAPOR PRESSURE of the substance, not by how many pounds of liquid are put into it. Vapor pressure is defined as the pressure of the vapor of a liquid in equilibrium with its liquid state. (Solids have vapor pressure, too, even though that seems odd at first. Just think of dry ice, which is solid CO2 but turns to vapor very quickly due to its high vapor pressure at room more.

Product Review of Digital pH Meter

Manufactured by Reef Fanatic

Product Review: Reef Fanatic Digital pH Meter (Written in 2004) When Reef Fanatic asked if I would be interested in checking out their new Digital pH Meter, I answered "of course" and then expected to see "a" Digital pH Meter! What showed up was far more than I expected! Envision a large "Duel" digital readout pH "and" Temperature meter. A meter that comes complete with a pH probe "and" temperature probe, and also a 9V AC adapter. And if that wasn't enough, there's also two packages of calibrating solutions, one for the pH 4 set point and one for pH 7 set point. I've had various brand more.

Q&A Letter Spotlight

Steven O'Loughlin writes to Bob about: Saltwater Disposal

Dear Bob, I would like to know if you ever heard of a problem to a septic tank or leaching field from wastewater from marine aquarium water changes? I'm concerned about the salt crystallizing and the other chemicals that would be present. I would also like to know about removing unwanted polyps, mushrooms and such from live rock. Should I re-cure it by putting it in a dark tank with powerheads and skimmer until they die off? I have some pieces that are really overgrown and they don't pull off very easily. I'm going to be moving soon and I want to make some changes to less free spreading more.
