After basically taking last swim season getting very frustrated and eventually mending pool leaks over the winter (July-September here!) I have now got a pool that's holding water, has been SO much easier to adjust seeing as my chemistry was moving around wildly due to constant refilling and all has been going swimmingly...
Except over the last few days the pool has developed a cloudiness. Now, I think it's calcium because, in my very old pool, the cracked tiles just above the waterline have a got a deposit on the cracks (i've chipped some off and it bubbles in acid). The calcium test also shows a reduction from 425 to 350 which is odd as I have not replaced 18% of my water! (I've barely had to fill at all since repairing the leak) also my pH is reducing, could that be because the calcium is precipitating out to solid?
My current test results are as follows:
pH: 7.4 (was 7.6 two weeks ago)
CH: 350 (was 425 two weeks ago)
Water Temp is between 28C/82F and 30C/86F
therefore CSI (from PoolMath): -0.19
Prior to the clouding, I had what I thought was a pretty well balanced pool with a CSI of around 0.08!
And searches I do to find out about calcium cloudiness usually suggest reducing CSI to negative, which I already am, so I'm at a loss firstly as to what has caused the clouding, and secondly what to do about it!
Any thoughts or advice would be very much appreciated.
