I have attached a picture of my pool. I have been living in this house for just over a week now and can't seem to get the water blue/clear. We have got it from brown, to an aqua like green. We have added shock 4 times, added algicide 3 times, put chlorine tabs in the filter, and have cleaned out that actual filter 3 different times. We have also put in our robotic cleaner and have taken him out to clean the bag about 10 different times, each time the bag has been filled with a black mud like substance. The water just will not get clear. This is our first time owning a pool so we are unsure of what our next step should be. Any and all input will be greatly appreciated. Thanks!
