Introducing the PPS-Classic
After numerous years of experimenting with aquatic plants and their requirements, reading endless opinions on the do’s and don’ts. It was time for me to do my own experiment using a system based on the knowledge acquired over the years.
The system which I refer to as Perpetual Preservation System (PPS) took many years in the making and many years of experimentation to fine tune, to document and to understand why some aspects worked and why some didn’t. I discovered that the reason why some of the systems I was experimenting with didn’t work was because it was a standard fix all cure. Water, fish, plants, biology and ones individual ecosystem that are created in your rooms are not standard, they are not the same, and they are not generic. Each has a life of their own and each is unique in both design and water chemistry. Accordingly, the Perpetual Preservation System was born from this idea. The idea that your tank is different, the idea that your tank is unique and that it requires unique attention is what brings us to where we are today in terms of aquatic plant fertilization and maintenance. Over the past months I attempted to get this point across in many posts here on APC answering a question at a time, a parameter at a time, a topic at a time which caused confusion. Your aquatic systems are not standalone; they can not be analyzed alone, they must be looked at in its entirety as a whole. Therefore, in order to help you and to those who want to push the limits of what can be attained and over the past few months working closely with Vic (also known as Discus), we have put together what we feel is an overall summary in the following articles. Although these articles barely scratch the surface of the work that has gone into the determination of formulas, the chemistry, and the biology, they are written to give the experienced and the beginner the basics to ensure their ecosystems thrive.
