As my recently filled water are low in CYA (Est. 20) and CH 60, I need to get both of them up. I am on both Trichlor and Cal-hypo. If my FC can hold at 3 by sunset (which seems to be doing quite well), I intend to concentrate on Cal-hypo to get my CH up.
Under normal application, it's best applied everyday or at least once every other day, right? But my being away from home all day (weekday) make it very inconvenient to dsipense Cal-hypo regularly so I decided to make a temporary dispenser to slowing add Cal-hypo when the pump is running. I dump a week's Cal-hypo in a plastic bottle and hang it over my waterfall. Adjust the flow rate to a trickle thus adding slowing. But the whole lot of Cal-hypo is soaked under water in the bottle until dissolved .
Now the questions are:
1) will there be any adverse effect to the soaked Cal-hypo for more than a week before dissolving and got mixed with pool water?
2) Though the mixture may not be very consistent ( I would expect the flow rate and mixture concentration to vary some 10-20% from reloading to finishing of Cal-hypo, would there be any problem if I try to maintain a slightly higher FC to offset any variation in flow/concentration?
3) with the Cal-hypo under water before dissolving, will the chlorine lost it's strength? There are two chambers of water all the time (upper chamber consist of pool water and some chlorine mixture and the lower chamber the water with dissolved chlorine and undissolved Cal-hypo). The inlet and outlet are both at the top.
This is only a temporary setup to last about 4 months just to get my CH up.
