What are these???

[waterflea]

In the last 2 weeks after rain the pool water rises and gets at the coping level. Today after rain stopped here is what showed up on my water surface. If anyone can help me determine what are these bugs I would really appreciated it . How can I get rid of them?
Thank you in advance.

Looks like Boatman bugs. Do some searches on YouTube to see if they look like what you're seeing. They typically thrive if there's algae in the water (that's what they feed on). If you have lakes of freshwater nearby, that's a likely source.

I have a pond nearby. I just did OCLT test in the last 2 days and it it negative. I keep my FC at 10ppm. The strange thing is that they don"t die in chlorine. How can I get rid of them?

Chlorinated water doesn’t really affect a lot of insects. You could try adding borates to your pool water to see if that affects them but it may not. I know wasps love my borated pool water ☹

My non-borated water too. Need to figure out how to reduce the surface tension so when they land, they drown.

I will try borate. Thanks!

They seems to be some kind of worms? Thoughts?

looks exactly like what i found in my pool after heavy rain couple days ago. never seen em before. I figured they came out of the overhanging tree branch but not sure. No other water sources near by. My FChasnt gone below 5 with CYA of 40, and no CC. i turned my skimmers/pump up and sucked em in to skimmer and they came out with the bouffant "skimmer sock" Greyish and very tiny, but they crawled up my hand fast when i touched the area.

Look up "springtails." They're a pain to get rid of.

Yes. You are right! Here is the confirmation Springtails in lawn, home or pool

wow, thanks!!! Thats them. Thinking back, i think the morning i found them was after the kids left the pool light on. i thought it was a small oil slick, but when i touched it, they sprung up my hand. very creppy, but glad to see harmless

here is an interesting link i found

Super Springtails - Field Station

Springtails are found on all seven continents, in moist places with leaf litter or soil (a few species have adapted to deserts, others to forest canopies, and still others prefer caves). They probably evolved in cooler climes, which explains their fondness for spring and fall, and they will...
