    Unexpected Rising TA

    Yes, I bought it from duda diesel.

    Unexpected Rising TA

    I was lowering my TA with MA and aeration over the past few weeks. It seemed to settle into a stable 70. Then, I added boric acid in 3 increments to get to 50ppm. My understanding is that borates shouldn't really raise your TA. I haven't added anything other than that since it was stable at 70...

    Effects of auto cover on water chemistry

    Ok. It was rather new plaster (~1 year old) when this was happening. So perhaps that was it. In theory, what can happen if you don't allow the CC and CO2 to off gas?

    Effects of auto cover on water chemistry

    I've tried scouring for all the answers I could find about how a pool cover would affect chemistry but still have a few lingering questions. It seems that a cover will generally reduce FC loss from UV. Additionally, it should slow pH rise since it cannot off gas CO2. Both of these things...

    OCLT in a jar

    Is it possible to take a sample of water into a jar and put it into a closet (or somewhere dark) for 8 hours to simulate an OCLT. Would the results tell you anything?

    Blue green stains

    So this says to circulate the pump on high for the duration of treatment. But instead you are saying I should start draining during treatment? That's where I'm confused.

    Blue green stains

    Is there a thread or link with specific instructions? Is simply turning off the pump during treatment enough to protect the heater copper core? Or do I simultaneously drain while using jack's #2?

    Blue green stains

    Just got my stain ID kit and it is indeed copper. I know that jacks requires a heater bypass, but does the zero alkalinity test also require this? I don't have a bypass but am reaching out to my builder to get it installed.

    Blue green stains

    Are there any options to clean it if I drain it first? I ordered the stain ID kit to try and confirm what it is.

    Is the Zero Alkalinity Acid Treatment an option here?

    Blue green stains

    When you say take the system offline, does this just means turning off the pump? I've never taken the cartridge out so I'll try and figure that out tomorrow. The tabs were in a floater. To be honest, chemistry was quite neglected for periods of time. PB came once a week but did not come...

    Blue green stains

    The system in the front is for the spa. It was previously using the pucks pictured below but I have switched it over to LC.
