I am happy with all my chemistry levels in the pool - they all within the recommended ranges.
FC is just dropping very slightly due to sunlight, I have a light blue pool cover and I think that stops a lot of Cl loss due to sunlight.
Swimming season is still at least 4 weeks away - nobody is swimming in the pool.
The water looks fabulous.
In the interests of saving electricity, can I run the pump for just 1 hour after topping up with liquid chlorine?
Until the weather warms up I want to just test my water about 7:00pm (ie after dark), work out the chlorine I need to add, add it and then run the pump for an hour to mix it up.
If it works out I have enough free chlorine and I don't need to add, why would I want to run the pump at all that night? This happened the other night, tested after a cloudy day and the chlorine levels hadn't dropped below reccomended.
Not much debris gets in the pool due to pool cover...
