    Getting Prepared to Balance Chemistry

    Thank you. I just picked up a four pack from Home Depot. $8.98 per gallon jug. Seems pricey but this is a journey of discovery for me. I clicked on your signature and then on your links but it takes me to the home page. I know that I am missing something - I want to follow rebalancing...

    Getting Prepared to Balance Chemistry

    My water exchange is going well. I have been pumping and filling for 14 hours and have already seen my values change significantly: From 0.5 free chlorine to 0.5 free chlorine From 0 combined chlorine to 0.5 combined chlorine From 7.6 PH to 7.2 PH From 110 alkalinity to 110 alkalinity From 575...

    Water Exchange: Cleaning Pool at Same Time

    Thank you for this information. My issue is that I have sky high calcium and CYA, so I am leery of ever using those tabs again. My pool store sells the refillable jugs of liquid chlorine that they say does not add CYA. Are these acceptable replacements for household bleach and/or Pool...

    Water Exchange: Cleaning Pool at Same Time

    Hi, I do live along Buffalo Bayou, and this is why I am interested in doing some extra scrubbing on the upper walls. I have some staining from the massive flooding from Hurricane Harvey. I do take your point, however, that I could address the stains once the pool is back to normal levels and...

    Water Exchange: Cleaning Pool at Same Time

    Thank you. Theoretically, how much water could be drained without pop up? I was thinking bring it down 1 to 2 feet out of 4 feet in the shallow end, scrub the walls, and then begin adding back in while I continue to pump.

    Water Exchange: Cleaning Pool at Same Time

    Hello, due to my high CYA levels I am going to do a water exchange. My diluted CYA is 80, so actually 160. I have a 15000 gallon pool so plan to exchange 2/3 of the water using a submersible pump. I have become perhaps overly ambitious now and thought that I might tackle some additional...

    Strange Stains

    Thank you for this. I performed the diluted CYA and found it to be 80. So 160. So looks like about half of my pool water needs to be exchanged. As another newbie question, is there an easier way to empty my pool? I generally hook a hose up to the faucet that sits between the pump and the...

    Strange Stains

    Should I address these little stain bombs as well? Or will lowered CYA help the stains to dissipate?

    Strange Stains

    The black dot disappears quickly, before I even hit the “high” range of CYA. Is there a link for switching to non calcium chlorine? I realize that I am adding calcium each tome I add this.

    Strange Stains

    Thank you. I edited my original post and added in my water chemistry and all of my current troubles. I am looking forward to one day being "trouble free". Thanks again.

    Strange Stains

    Over the last two weeks, I have been experiencing brown stains on the pool plaster. I thought it was fertilizer stains, perhaps blowing over from a neighbor yard, and the only thing that would remove the stain is a diluted muriatic acid application directly to the stain. Then, usually each...
