Hi! I am new to this forum and I joined because me and my father recently opened our pool for the summer, and we have been vexed by this strange problem we've never encountered before. The top of the water is covered in foamy bubbles that just wont seem to go away. We have already tried half empying the pool of water multiple times. We have also used a whole bag of salt for the pool (because we have a power ionizer for salt water). We washed the filter rings 4-5 times. This problem has been around for 2 to 3 days now and it won't go away. We are asking for help urgently because the people at the pool store are being useless and unhelpful. I have attached an image of the water, any help would be greatly appreciated.
