    Can I use up my CalHypo?

    After finally getting my CYA under control with a year of nothing but bleach (Clorox) can I use up the 73% CalHypo I have from the pool store as long as I follow PoolMath? No stabilizer there right? Thanks.

    No but you are adding calcium. What is your CH reading?

    Can you post a full set of results? How hard is your water there?

    Okay with me. Can anybody watch that? I could bring Calvin if he has interest. Went by your house today but didn't have any balls. Looks like and underground pipe broke in your area.

    Re: Can I use up my CalHypo?

    From your numbers and I've assumed water temp of around 60F, you are around -0.4 CSI so that you means that you should be right to add some CalHypo. How much have you got available/planning to add?

    Your CSI number will also go upwards as the water warms up but then you can then work on bringing your TA back to 60 if is starts getting too high which should also help to stabilise the upward movement of your pH.

    Really, I should just dump it right?

    Re: Can I use up my CalHypo?

    I think the best way to do it is grab a bucket and fill it with water and pour in the CalHypo and mix well. Pour it in front of a return and any undissolved stuff sitting on the bottom of the bucket just refill with water and repeat the process until it's gone. If any gets left on the bottom of the pool just brush it up.

    No I would use it - it should be fine to use. Just be careful of how much you dump in.

    How much cal-hypo are we talking about? One pound (16oz) of 73% Cal-hypo will add 6.2ppm to FC and 4.4ppm to CH. If you used 5 pounds over the course of a few weeks you would add 22ppm to your CH.

    I would spread it out over a few weeks as in domct203's format when you need a shot of Chlorine.

    Thanks everyone. I'm going to dispose of the Cal-hypo and stick to bleach. Why mess with what works?

    It works just as well. Obviously your business, but I would rather use it than waste it.
