Sounds good confusing me with someone else, but these "critters" as you put it, are what you have to deal with, they are the proper names of these "critters" in your pool water.  Education can useful sometimes.
But getting back to the original subject matter, three months in I am still running my pump for an hour a day, spending and hour a week cleaning, getting through about 1 tablet a week = 2-3ppm, water temperature low, a small amount of water loss and still the water is pristine, chemistry spot on. The walls are completely slime free, with nothing in the trough either, so everything going to plan and easy to monitor.
One thing I didn't mention is that I used a very pale blue tile, which shows up every speck of dirt, or the minutest tinge of green, so when it is clean you can see. Not to everyone's taste, but this is all about efficiency and clean water.

Jan-Feb Costs
1. I just got my electricity bill, the first since I stopped messing around and what a pleasant surprise, only an extra 0.8 units a day = 3baht for pump and lights.
2. Daily water losses equate to about 2mm, covering a lower than usual level of evaporation, which could have been up to 8mm without the roof = 1baht
3. I bought a box of chlorine tablets 10 days after I filled the pool, which cost 3,600baht and 24% is used up in 75 days, so that = 11.50baht day keeping the level at between 2-3ppm.
So my pool is costing about 15baht/day in total to run and keep pristine, add to that 1 hours labour per week for cleaning and a current water temperature of a cool 28c, I am more than happy.
Apart from a time switch, there are no automatic systems on my pool and I see no need for them, I vacuum the pool one a week, wash out the bag filter, add a new tablet and all that can be done in 1hour or less. As a result there is nothing to maintain or worry about, just check 4 parameters every few days and enjoy a cool swim.

Yes indeed! I did confuse you with another, the one who touts magnetic pulse technology for water treatment. So for my oblique suggestion, I apologize.
As far as my education, I have some -- not nearly enough -- and will continue to learn from folks who really know what they are talking about. You see, I have some experience in water 'filtration', having been an industrial sales rep for one of the earliest manufacturers of RO. I called on lots of facilities engineers who had visits from peddlers touting all sorts of magical and unique cures for removing dissolved solids and biologicals. Saw many companies burned by quick fixes.
BUT -- getting back to your original claims -- still emblazoned in bold type above -- your are partly correct in you descriptions, also partly wrong.
Legionella phneumophila and Psuedomonas aeruginosa are, according to Wikipedia, bacteria .. congratulations
However
Escherichia coli is not a parasite, but a Gram-negative, rod-shaped bacterium that is commonly found in the lower intestine of warm-blooded organisms (endotherms).
So maybe before you decide to challenge my education, you might want to do a a bit more reading
BTW, a trusted resource for water-borne "critters" http://www.ncbi.nlm..../pdf/100067.pdf
Cheers!

and if one has a reasonable amount of "critters" in the pool one puts up a sign "Critter Zoo" and collects entry fees.
nota bene: Farangs pay double!

I accept you apology and also submit a correction of my own, I should, as you pointed out, have included E.Coli under the heading of Bacterium, instead of parasites. Perhaps by us highlighting these issues many more people are now aware of what exactly they are dealing with in their pools.
I do not feel I have any association whatsoever with the conmen you describe.
1. I am not selling anything and have nothing to gain.
2. I put forward in detail my reasons for the choices I make, with nothing that could be construed as misleading, save for the odd error, now corrected.
3. The filters I use have no magic properties they are merely made from a material, which due to weave design, has a particular pore size and stops everything that is larger in size.The material used is highly suitable for use with chlorinated water. Bag filters are already used extensively in this and other industries and in my view, are superior in almost every way to the much more expensive and complicated sand filter, currently being sold here.
