We have seen some water loss, we are going to do the bucket test tonight. We did find 2 tiny holes in the liner and we used a vinyl repair kit to fix those. Also, we do have a light fixture in the deep end of the pool which seems to be pretty loose. First, can we replace the light under water? I wasn't sure if this was encased in something that allowed us to be able to do that. Also, should we just go to the pool store to get screws that would allow us to tighten that?

Since the pool is cloudy, does increasing the pH help to fix this? Sorry for all of the questions! We’re still trying to figure all of this out.
