Going through a basic PPM calculation by volume or by mass will help to cement the concepts you need to understand. For mass, imagine you have 0.98 liters of water with 0.2 g of salt dissolved in it, noting that 1 L of water = 1 kg of mass, so the total mass in the example is ...

Today, I’ll guide you through identifying and treating Ich to save your fish’s life. Ich, short for Ichthyophthirius multifiliis, is a common aquarium disease caused by parasites that appear as white spots on fish. These parasites can easily transfer from tank to tank via fish, plants,...
Once you understand how infrared detects light, then you can start composing images. Much of the success of infrared portraits is understanding how to separate subjects from their backgrounds in what can seem like an upside-down visual world. For example, placing a figure in front of a clear ...
The very first time you pH your water, it will take a little trial and error to figure out how much PH Up or PH Down to add to get to the right number since everyone’s water is a little different. The general idea is to start with a little bit, maybe a few drops, then retest...
I found some configuration options and played around with"certname","node_name"and"node_name_value", but I couldn't get the delay to go away. Does anyone know specifically how to either tell Facter to ignore the fqdn or how to make Facter able to find the fqdn on an Ubu...
