    Weight vs Volume

    I need to add some stabilizer to get my CYA up today. I need to add 40 oz by weight or 41 oz by volume. The only scale I have is a bathroom scale. Do you measure volume by using a measuring cup and adding 41 oz in the cup?

    What does the Container of CYA say? How much is left. You don't have to be exact.

    A 10% variance on your dosage will be fine.

    Yes, but you will never see the difference of one ounce Cya in nearly 15K gallons of water. Even if you have the gallons nailed down to +\- 5 gallons. Put it all in there, and an ounce or two extra if you wish. It simply won't make much difference you can see on the test.

    Re: Weight vs Volume

    My container says 5.5 lbs when new. I weighed myself, then did it again with container and it has 4 lbs remaining. I need about 2 1/2 lbs, so I will be doing some more weighing here in a few minutes to get my amount right, and CYA from 50 to 70. Thanks guys!!!

    Always tweaking I see.

    Nothing wrong with that at all. You've got it down, so no worries there.

    My wife says I'm crazy! But she sure loves getting into a sparkling clear pool..........
    I guess I have another question though, and I have addressed this before. Water temp is at 68, with several warm days coming then a slight cool down (again). Should I just stay at 50 for a while longer while using bleach? I still haven't started the SWG or put the solar cover on because it is too cool.

    I would if it were me. If you get any warm up in water temp, throw on the blanket to save it.
