Hi! We just opened our pool about 2 months ago and up until now it was going great. Just the past few days we noticed these grey bugs crawling on the steps, then realized they were all over the bottom of the pool by the drain in the deep end. I've been googling bugs in pools all morning and can't find any pictures of the bugs we have. They do not look like back swimmers or boatman. They are maybe half an inch long, grey, but not smooth. Kind of diamond shaped bodies...my husband said the ones at the bottom are dead. There are HUNDREDS of them. Yesterday they were all over the walls in the deep end but this morning they seem to mostly have fallen to the bottom, some are still stuck on the walls but not as many as last night. We just moved into this house and filled the pool with new water just this season. We have it cleaned and checked once a week and we skim it every day. We don't vacuum it, could that be the problem? I also don't know where these weird bugs are coming from. We live in a wooded area so there are lots of trees in our yard and it was raining almost every day last week if that makes a difference? Hopefully someone can help me identify these bugs and a way to resolve this, I'm so freaked out by it! Thanks for taking the time to read
