One of the Secrets is constant flow rate, which is achieved by special diffusers at the bottom of the filtration zone, which distribute the water evenly up and through the filtration layers. Gravity fed Filtration systems do not work for long, as the sediments start blocking the fine pores of the filtration granulate and alter the flow rate of the water passing through. If the flow rate of the water is too high, the micro biology cannot grow and the water will pass through unaffected – if it is too low, the microbiology dies off, the water will start rotting, floating algae and mosquito larva can occur.

The flipping e-book “How to build a Natural Filtration System for your pool or pond” will enable you to design and build the Natural Filtration System for your pool or pond.

This document is considered the “bible” for Natural pool building. All this knowledge used to be only available to a limited number of installers after extensive training and is considered as “Secrets of the Trade”.Now this e-book has been rewritten for Self Study purposes. It covers the general ground rules for design of a Natural Swimming Pool, Construction, Installation of underwater extraction, Filter zone, pumps and pipes and much more…

Now this insider knowledge has now been made available for you to download and study, then either build pools for others or for yourself. And if you pass it on to your pool builder and tell him “This is what I want!” that’s fine too!
