Having successfully completed 2 SLAMS in the last 3 months, the last one finishing about 4 weeks ago, I am getting warning signs I got before - i.e. SWG losing too much, very slightly over time.
Two weeks ago, we were having the house painted on the outside, and as part of that, they power washed the whole pool screen. There was all sorts of debris in the pool after - leaves, dust (when I brushed it , I got brown clouds) , flakes of old paint etc. I did chuck in some bleach and raise the FC to 24 before they started. Of course, there could well be a whole bunch of stuff that washed in the pool that is not even visible to to the eye.
Anyway, I left pump running but SWG off, after they had finished , to let to FC naturally drop, over 5 days. Once it got to 10 , I put on SWG on 20%. Pump run time the same - 10am to 6pm.
These are results:
8/5
12.30 pm
fc 10 - swg 20%
changed to 30%
---------------------
8/10
10 am
fc 9
swg 40%
---------
8/11
10am
fc 9
------------
8/12 and 8/13
10am
fc 7.5
SWG 50%
--------------------
8/13
6pm
fc 6.5
swg 60%
-------------------
8/15
10.30 am
FC 5
I know I need to do an overnight AGAIN, but other than this worrying drop with increasing SWG %, anyone think of anything else it could be. I am pretty sure, I am going to have to do yet another SLAM - as the signs are the same as before. Just turned up SWG to 80%, will test again today at 6 pm. It should go UP not down , if everything is ok.
thx
