FAQ's

This is a selection of some of the questions we have been asked over time regarding the Natural Filtration Systems:

Q1: Why does the water not have to be changed?

Q2: Why is the exact flow rate of the water through the filter so important?

Q3: How hot can I run the pool?

Q4: Can I use solar heating in the pool?

Q5: What size is required for the filtration zone?

Q6: Can I use bore water to fill the pool?

Q7: What services does Aquaviva Australia provide?

Q8: Does a Natural Pool attract Mosquitos?

Q9: How about bio-film in a Natural Pool?

Q10: Can I use tiles in my pool?

Q11: What is the best surface for my Natural Pool?

-----------------------------------------------------

Q1: How often does the water have to be changed?

A: Never. The plants in the filtration zone feed from the dissolved nutrition in the water which is a natural occurance from leaves, dust, etc. Chlorine is only suppressing the availability of the nutrition as food for algae. When chlorine application is stopped the water might turn green within a few days. After time more and more nutrition has to be suppressed by more and more chemicals - and eventually when the water is "unbearably unpleasant" it has to be exchanged. We've had pools operating for more than 15 years in Europe and the water was never changed. One system in Australia has been running for more than 3 years, also the water was never changed. Topped up, yes, because of evaporation. The simplest is to connect your roof downpipe directly into the pool with a shut of valve/diverter or overflow from the pool.

Q2: Why is the exact flow rate of the water through the filter so important?

A: The Microbiology living in the porous filtration substrate binds the nutrition in the water and makes it available for the plants in the filtration zone as food. Therefore the dissolved nutrition in the water is removed which otherwise would be food for algae.

Q3: How hot can I run the pool?

A: The Microbiology living in the water can defeat all the bad bacteria up to 28 Degrees Celsius permanent water temperature. If it goes above 28 Degrees Celsius a few days/year it does not matter, as long as the water temperature is generaly lower.

Q4: Can I use solar heating in the pool?

A: Yes, but there are a few things to consider. eg. As you are pumping Natural Living Water through the solar system, the water will go beyond 28 degrees in the pipes. If it sits on the hot roof for too long, bad bacteria can grow, which are flushed back into the pool. Eventually the Natural Filtration System will take care of them - but it's better to drain the solar system if not in use.

Q5: Can I use solar heating in the pool?

A: Yes, but there are a few things to consider. eg. As you are pumping Natural Living Water through the solar system, the water will go beyond 28 degrees in the pipes. If it sits on the hot roof for too long, bad bacteria can grow, which are flushed back into the pool. Eventually the Natural Filtration System will take care of them - but it's better to drain the solar system if not in use.

Q6: Can I use bore water to fill the pool??

A: In pricipal yes, but it has to be tested/confirmed first for no salts, sulfates, etc.

Q7: What services does Aquaviva Australia provide?

A: Our extensive manuals provide the owner builder or pool builder with all the knowledge to build Natural Filtration Systems, which suit all types of pools applications. Aquaviva supplies the required essentials for the Natural Filtration System only. The pool building itself - we leave that to the experts. If you are a pool builder or landscaper and would like to get involved with this Exciting New Technolgoy, please contact us.

Q8: Does a Natural Pool attract Mosquitos?

A: Simple answer, No. The Natural Pool system is considered to be moving, natural, living water. Mosquitos prefer static, anaerobic waters like puddles.

Q9: How about bio-film in a Natural Pool?

A: Bio film is a natural occurrance in living water. Even every crystal clear mountain lake or creek in the Alps grows bio film to some extent. But its also a question of the amount of nutrition in the water. Just because the water is crystal clear does not mean there is no nutrition dissolved in the water. If you can keep the amount of dirt, dust, leaves, or other organic matter getting into your pool to a minimum, then little to no bio-film will form. If it does occur, it is quite simple to remove with e.g. a Creepy Crauwly..

Q10: Can I use tiles in my pool?

A: Generally, the smoother the surface the better. The lighter the color the more will any dirt, leaves or dust show. It's like a white carpet requires more often vacuuming than a darker one. Tiles are generally no problem as they are smooth surfaced, but the concrete based grout can be, as it is porous, and bio film can grow which is hard to remove between the tiles. Acrylic based, non porous grout is fine - but then there is still the gap and the difference in the levels between tile and grout. We have seen granite, natural tiles in some architectural pools, laid gap free. Another advantage of granite is the grainy appearance, which camouflages dirt or dust at the bottom of the pool better than eg. light blue tiles..

Q11: What is the best surface for my Natural Pool?

A: Generally, the smoother and darker, the better. The lighter the color the more will any dirt, leaves or dust show. It's like a white carpet requires more often vacuuming than a darker one. This is why for many Natural Pools liners are used, as they are easy to clean with eg. a Creepy Crauwly. .
