    Debris found in water return -- what could it be?

    Water is clear. Pool has been open all winter with SWG/pump running 4 hours per day, 40% SWG. Extended hours with the time change back up to 10 hours. Today I added salt, acid, stabilizer & bleach to start improving my numbers. When I went to pour acid in pool at the water return jet, I noticed this white, flat particle wedged across the return. As I went to remove it, it broke into smaller pieces. Attached is a picture of the fragmented pieces. Would like to hear folks thoughts on what this might be and how it formed in my pool. Thanks.Attachment 59719

    pour a drop or two of MA on a piece and see if it fizzes up. It would be calcium if it does, I believe?

    Interesting pattern.. does it match your walls or anything?

    How old is the pool? It looks like some excess plaster that was caught in the plumbing and finally got pushed out.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    It definitely bubbled when I put a bit MA on it. Before I broke it, it was probably at least $.25 size, but as you can see flat. It is an interesting pattern, but I will have to wait for daylight to see if matches the plaster. I don't think so, but I haven't didn't have a reason to look that close before.

    The pool is 20 years old, and could use new plaster. I was concerned at one point recently due to the skimmer basket intake seeming to have low intake pressure. I ended up using a pressure bulb to push water back from the pump side to skimmer basket. Seemed to have sufficient flow, but I kept the other valves less than fully open to make sure it was removing leaves, and hoping the pump skimmer would catch whatever broke free. That was probably very late 2016.

    Can you recheck or is its a mistake

    Hmmmmmm.... I guess I gotta wonder if Richard is correct and it was plaster in the lines finally (FINALLY!) breaking loose and coming out. You've looked at your SWG for scaling, right??

    ok, so sometimes the simplest answer is the right answer. Guess I didn't realize I had gone that long without checking SWG. Check out these two beauties. ---ooops photo exceeds size limit. In length, they each exceed a US. $.25 by a 1/2 inch. In width the quarter slightly exceeded each. SWG now soaking in MA-Water solution for a nearly an hour; still bubbling.
