We recently added 3 new articles to cover some of the more general questions we get asked. They cover basic topics and you can find them here:
Saltwater Aquarium Parameter Chart
What is Berlin Filtration, or what is a Berlin Filtration System?
How to Start a Siphon, tips and tricks.
A few tips can be found in the siphon article if you are still doing it the "old fashioned way" you might find helpful. I will add some pictures to help illustrate the concepts by the end of the week, when we publish the next set of articles. If there are topics you would like to see in the future, (even if just for handy reference), let us know and we will make sure to get and article on the website soon.
