I opened my sand filter to perform a deep clean in preparation for opening the pool for the season and I noticed that my filter sand is a very dark brown / black color. It doesn't look like the sand in the TFP deep cleaning video. I replaced the filter sand when I bought our house about 6 years ago and the old sand did look similar. I thought it was a different type of filter medium that the original owners used and I just replaced it with new pool filter sand. It doesn't look anything like pool sand I put in. During the day my pool normally looks pretty crystal clear. At night with the pool lights on, it does have a slight cloudiness to it with fine particles floating around.
So my question, is this normal for pool sand? If not, is there anyway to clean/refresh the filter without having to replace the sand?
My pool is approx 30,000 gallons with well water and swg.
Thanks.
