<p>I would venture to say those crystal waters are the other end of the extreme. Clear yes but still devoid of life.<br>
and containing an invasive species is no small thing.<br>
Not to say natural pools don't have animal filters. But you need the surface area. <br>
Suggestions?</p>

Foam would be a great colonizer but I want to stay away from synthetics<br>
given that it is a long term swimming pool and I don't want to worry about leeching.<br>

I remember years ago about this time (ie late May-early June) when I used to build vacation homes during my summer work term during university ... bathing in the f-f-f-f-f-rigid water of the northern Ontario lake after a long, hot day of feeding the mosquitoes and blackflies (ostensibly while working) -- in one there were honking-big leeches wriggling around in the still,black waters.<br>
Gnnnna-a-aa!<br>
<br>
But I digress.<br>
<br>
I also remember that when I left my home town on the Bay of Quinte to go away to university, the waters of the Bay were pretty disgustingly polluted. This was at time when rivers in the Rust Belt states in the US would catch fire -- environmental awareness wasn't big on people's minds back then.<br>
<br>
I was surprised a couple of decades later while walking along the shore of the Bay on a visit to the home town, to see that the water was crystal clear and the shoreline was free of the scummy crud that used to collect there.<br>
<br>
My cousin, a avid fisherman revealed to me that Zebra Mussels were responsible for turning that once pollution-filled water into sparkling, crystal-clear water.<br>
<br>
The thought occurred to me that those randy little mollusks might be useful as bio-filters for closed systems like swimming pools where there wouldn't be any aquatic life dependent upon micro-organisms in the water to sustain them.<br>
<br>
I would imagine that there are no shortage of Zebra Mussels in the NYC area making themselves a Major PITA. The biggest challenge it would seem, is how to ensure that they don't escape from the confines of the "pool" system.<br>
