So here goes again having a pool through monsoon season in Thailand has been interesting over the last couple of years this is the first year with the SWG and after nearly any heavy downpour (can get upto 10cm of rain in one go) i get the salt low light on the SWG i have been testing it with tablets but i use 20 plus tablets every time (see previous posts) but without really knowing at what ppm the light comes on its been a battle so ive turned it off and gone back to liquid chlorine at the moment .I should of bought a SWG with a salt ppm readout on it would of made life much easier in the monsoon season .
i was thinking maybe ill buy a salt pen then i can test much more regular and keep the salt in check for the SWG the salt is cheap here i live 10km from some salt flats it costs £3 for a 40kg bag
the 2 options for the pens that i can get are
Products - SD 80 TDS - Lovibond
Palintest PT 158 Salinity Pocket Sensor
Pocket Sensors | Palintest
anyone on here used either of these or have any thoughts about either model
thanks in advance for any replies
