Hello everyone! I just bought my first home and it has an in ground pool. I have no knowledge whatsoever on pool maintenance but I’m willing to learn. The previous owners left me nothing so I have no clue what I need to do or even what I have. I know that my pool vacuum doesn’t work but I can’t tell if it’s cause of the vacuum or the pump. I noticed today algae on the walls and I have a test kit I found in the pool supply closet. I’ve included pictures so hopefully someone(s) can help me!
