    What is this Stain? How to Remove it?

    UPDATE: I ended up going with a combination of Vitamin C and Muriatic acid - though not at the same time.

    What is this Stain? How to Remove it?

    I do not have any vitamin C (without going to buy it). I do have Muriatic acid. Would you recommend me using that? I use it for pH control in the pool which does not have stain issues.

    What is this Stain? How to Remove it?

    I'll get some and give it a try. How soon will I notice a difference? Seconds, minutes, hours, days? If that doesn't work, do you have another recommendation?

    What is this Stain? How to Remove it?

    I just took the cover off my hot tub and noticed staining as seen below on one half of my hot tub. What caused it? How can I remove it? I've tried bleach and Mean Green but that did very little. Thanks! Steve

    Air in Return - New Filter??

    Good to know. So I will have to order something instead of use what I have around the house? UPDATE: I tightened the drain plug earlier and I did not see a difference. Went outside just now and at first I thought my pump was messed up. I was used to hearing the returns and seeing the air...

    Air in Return - New Filter??

    Yeah, I didn't do that. I do not have any pool lubricant. Do you have a suggestion for something around the house that will work such as Vaseline?

    Air in Return - New Filter??

    I have not looked at the drain plug but will do so. The ring on the basket lid is new but I'll do the test and pour water on it to see if that happens to prevent bubbles. The skimmer weir appears to be working as it should. It floats and isn't stuck or blocked nor is their a vortex that I...

    Air in Return - New Filter??

    My equipment is old but I have only owned the house for two years. Last year I replaced the multi-port valve with this (Top Mount Thread-Praher (tm-12-a) - INYOPools.com ) All worked well last year. Starting this year (after winter), there is constantly air in my return. I have to prime the...

    Algae or Another Big Problem?

    So if I see a slightly dark dirty substance at the bottom, is it safe to assume it is dead algae resting on the bottom?

    Algae or Another Big Problem?

    SLAM - Now What?? I've been in the process of slamming my pool for the past few days. I passed the overnight test. Does dead algae float or sink? Can it come back to life? Tonight will be the first time I've turned off the pump since beginning the SLAM. Do I need to add a classifier or FLOC...

    Algae or Another Big Problem?

    I had virtually no dropoff overnight but did not keep it at 16 the entire time as CYA is 35. Rounding up to 40/16ppm would have been ideal. If I did not have dropoff, should I be ok to allow it to go back to normal levels?

    Algae or Another Big Problem?

    I've maintained a minimum of 12FC for several days. WHen I brush the the bottom, I see just a tiny bit of algea in the finishing stroke of the brush. Does dead algea float or sink? Is dead algea still the same color or does it change? I'll do an overnight test tonight.
