how do you guys major the grams of HTH pool shock?
I wanted to make the 24gram/gallon soloution but perhaps just 1 quart or half a gallon, 1 gallon would take a while to use
ceramic airstones they come in 4cm diameter for cheap or 8 and 10cm for more money
you need 1-2W of air pump power per gallon of water
so for 5gallon you need an air pump with 5-10W power
I have not seen anything around 10W that is not commercial
