    Flagstone Border Decay / Chipping

    Hi All, I have a pebbletec pool, with what I believe is a flagstone border at the top edge. It appears as if the flagstone is chipping off and decaying -- I even found a quarter size chip of it in my pool vacuum. I'm going to assume this has to do something with CH as my pH is usually...

    Pool Light Safety

    Recently the local (and some national) news has been reporting in injuries and deaths from malfunctioning pool lights. While I believe properly installed pool lights are likely safer than driving to the store to get bread, I thought I would ask the experts. What type of regular checks should be...

    Hand turned color?

    See below picture, not sure how this happened but I only have one theory. Theory is that I was doing weekly testing (all tests in TF100) and spilled something on my hand. I didn't notice until we were actually swimming though, so maybe something in the pool water reacted to it? Soap doesn't...

    Is PH of 7.8 too high?

    My PH seems to creep up to 7.8 and then remains fairly steady -- just wondering if I can leave it here provided I keep close watch. Also, my CH is slowly trending downwards - It has gone from 275 to 225 in a month -- I suspect this is because my fill water is after whole house water softener...

    Cartridge Filter Leaking on Startup

    Upon pump start up, my cartridge filter leaks for about 10 seconds then completely stops. I've used a health amount of magic lube on the O ring, and that seems to help a little. Not sure if this is normal or not (I suspect that it is not.) Is it time just for a new O ring?

    Efflorescence, Salt or Calcium

    Can someone tell me what this is? Its constantly on my rock wall and border. 5 to 1 diluted MA reacts with it a little bit, bit doesn't seem to clean it very well. (I'm not sure if its just reacting with the soft stone or if thats possible though.) Anyway to clean this off and keep it...

    Dump used reagents in pool?

    I know the instructions say not to do it, but do any of you clean testing vials etc in the pool after testing? What type of harm would this lead to?

    CC Test Question

    When testing for CC with the TF-100, how pink does the water turn if you have any CC? I suspect that it turns back to the original bright pink. I've never had that happen, which is likely due to my light load and SWG. Just checking.

    Calcium Scaling?

    I have a spa that overflows a rock wall ledge into the pool. In the mortar between the rocks I am noticing what appears to be white calcium scaling? Scrubbing with stainless brush removes a small bit. (very hard scrubbing.) Whats the best way to remove/prevent this? Current Test Results...

The hairline cracks are leaking minuscule amounts of...

    Long Term Maintenance Costs?

    Since I'm new to having a pool, and most of the immediate stuff under control, I'm starting to wonder about long term maintenance / upgrades that will need to be done. The pool was built in 2004, and from what I can tell, not much has been done to it, other than keeping the chemistry correct...

    Inspecting Auto Cleaner / Proper way to not lose prime?

    Hi All, Is there a "proper" way to inspect the bottom of an automatic pool cleaner that doesn't suck air in? Should I not be running the pump when I do this? Currently, I pull it out of the water for 15-30 seconds, look at it and put it back in. Air does get sucked in, however I am not sure...

    Black and White Stains?

    Hi All, Just became owner of this pool approx 6 months ago, so unsure of the chemistry history. There are stains? that have been on the bottom ever since I've owned it -- I think that these are just cosmetic and am looking for verification. I'm also wondering what they are, and if it can be...

    What to tweak?

    Valve Settings for Floor Drain + Vacuum + Skimmer

    All - First post here, the forum and pool school as been incredibly helpful. I've learned so much. After purchasing a house with a pool, we had a local pool service company come out and do a check up on it. One of the things that the service guy said (and changed) was that because I have...
