Stinky Water - My Pool Smells Like Poop

[PoolDoc]

Very interesting, Waterbear.

I've seen black sand like that, but not had any problems after initial clean up, but then I had low CYA on those pools. After the OP does what you say, using trichlor tabs in the skimmer could help continue to clean up any remaining pockets.

Another possibility might be ground water seeping in through the bottom drain. If the ground water runs through a sulfur vein it certainly would carry a bad smell. Bleach and more bleach.

Possible, I suppose, but only if the main drain line is cracked. Normally if that's the case, you'll have a pretty serious leak when the ground is dry.

We do not fill from a well but instead from city water. We will start to bring up the fc ppm to 20 and will also open up the filter. Is there a trick to opening the filter we have never done it before.

I hope we done have a main drain leak. We have had lots of rain so I will wait for a dry spell but not sure where I would check the ground to be damp. Any thoughts here would be appreciate.

I will share results once we start to get chlori e up.

Thanks all for the insight!

Yes. Tell us the exact make / model, or send pictures to poolforum@gmail.com.
