Hi guys , thanks to those who steered this newbee in the right direction a while back .
So , SWG and pH doser installed and working as expected , here in a sunny northern Spain .
I run the SWG at 50% , no need to add any muratic acid in the first 2 months since pool re-build , and it is peak summer weather right now .
The pH doser has maintained a rock steady level at all times .
Not even had to add any more salt yet .
What is problem then ?...... I hear you ask !
I have just replaced the ancient Hayward pump that ( when in use ) had been likened to the noise of the space shuttle during take-off .
The new Hayward 1HP Max Flo XL variable speed , which came with all the usual manufactures claims of saving electricity due to the permanent magnet motor .. blah , blah ,blah !
I liked the idea to run it 24/7 ( as Hayward promote ) so I could generate salt/ chlorine during the night , as ( apparently ) this is the best time to do so .
I have set the pump at 1200rpm for 20 hours , and 2400rpm for 4 hours . surely enough for 48m3 pool ?
The bit I did not consider is - the pressure on the 600mm sand filter would drop to just above zero when at 1200rpm - this lead me to think ......would the filter be functioning correctly ?
Surely its water passing through sand - just slowly - but for an extended period - therefore enough .
Doing some research on this site ( and elsewhere ) I am now more confused than ever .
There is no cost benefit of night-time electricity , and most here do the 8 hours at motor full speed method .
Spain can be slow to pick up on new ideas , and most pool owners here are rich and get the pool guy to do it all so have no clue .
Sadly I do not have this financial benefit , so need to ask for help . Cheers . Spainboy .
