We recently had an inground pool completed and although the builders gave us a demo it was a little short and we still have questions that theyre not answering that well. Being our first pool its getting use to how it all works is a problem.
Firstly, the return outlets seem to make alot of noise a kind of crackling/popping sound, i`ve traced it to the sound coming out of a hole above each outlet just below the pool surround tiles. If you put a finger over the hole its much quieter. I`ve noticed some water coming out occasionally from these holes. The builders said the noise is because they are new and it will go after a while but its been on two weeks and still noisy.
Secondly, we have a sand filter system. When leaving set to filter is it best to leave the skimmer and/or the main drain filter at the bottom of the pool going. Reason is that the pool is still pretty murky, i`ve cleaned it quite a few times but sedement keeps collecting at the bottom of the pool. I leave the filter running for about 5-6 hours and then have to clean the bottom which just sturs up alot of the muck.
Finally, We came back after a few days of storms to discover flying ants all over the surface of the pool and a kind of brown scum. it was discusting , anyway its left a brown tide mark around the edge of the pool. Any tips for cleaning this off, i`m thinking of using an old toothbrush to get rid of it. Its a painted concrete pool so dont want to damage it.
