Update on New Pool

[Simon]

I promised in a previous post to give an update on our new steel liner pool which has an Auto-Chlor  and pH- peristaltic pump control system (as opposed to a Saltwater system).  The filter system is sand and the pump circulates the water every 4 hrs (I think).  The pool is approx 10mx5m and average 1.25 metres deep.

Poolguy (I believe) recommends the Auto-doser system (although I think he prefers a different (vacuum?) type of pump) - however assuming the pumps work then the process (and results) should be the same. 

We left the system unattended and with a summer/winter security cover on for 4 weeks between beginning of Juy and beginning of August.  Removing the cover was was a surprise - the water was very clear although there was a film of slippery deposit on the floor.  The Auto-chlor system appeared to have tripped out at some point with a "max dose" error as had the pH-.

I cleaned the pool floor and sides and over the next 3 weeks tested the pool regularly.   The Auto-chlor system kept failing with a "max-dose" error and we seemed to be getting through a lot of Javel, but I "choc'd" the system a few times to get some stabiliser into it (I now understand I can get the cyuranic acid directly ("stabilant") during the time we were there.  I think we went through about 30 - 40L of Javel 9.6% whilst we were there. 

The bottom line though was throughout the 3 weeks we were there the water was sparkling, we could easily see the bottom and the water did not have a "chlorine" taste or smell.  I had to clean the floor a little but not too much as the slippery film (which looked like extremely fine sand and I assume is some form of Algal growth) appeared about 4-5 days after a floor/side clean.

I have a Coolpool tester and would thoroughly recommend this as it is very easy to use and indicated the level of Chlorine and pH.

For the auto-dosers I have now re-programmed these (after reading the French instructions) so that there is no "trip" for max-dose and hopefully this will manage the process better (rather than me having to re-set it) when we are away.

We have now covered up the pool again and left it for 4 weeks again, so hopefully the results will be better if the chlorine level is maintained.

I still think I need more stabiliser in the pool and I definitely need to increase total alkilnity which tested "low" on the Coolpool tester.

However, I am (so far and early days) pleasantly surprised by how easy it is and the fact that you can leave the pool to itself.  Admittedly with the cover on this will exclude most light so the chlorine should not be eaten up by the UV and will help with reducing algae.

Of course the best bit is diving in when the temp is 35C.  But I guess that's why we have a pool.

You've answered most of my questions here from your earlier post.

Glad it all works.

Just keep the stabilser between 30-50ppm, so if you get a lot of rain

then check again and adjust. About 1 bidon every 4-6 weeks depending on

temp, bather load and volume is about optimum.
