Hey everyone just wanted to introduce myself and ask a few questions, also very grateful to have found this community. I just bought a house with a pool, first pool I've owned but I've grown up taking care of pool in most houses we lived in so not totally new but no expert by any means. First issue, no one was living in the house when we bought it and the way the investors were keeping it chlorinated was filling the skimmer basket with chlorine tabs with the pump running 24 hours. As you can imagine this destroyed the intelliflow pump that it had, destroyed the seal and corroded the housing so bad it fell apart when I tried to rebuild. I replaced the pump with a jacuzzi VSP (not my first choice) but I needed this fixed ASAP and most pentair pumps were weeks out shipping. Added chlorine to get over 5PPM FC and acid to 7.4 PH, I tested CYA but I initially thought I did something wrong because the dot disappeared before I got anywhere near 100, now from reading here and them using all those tabs.....it probably is sky high well over 100. The water is pretty clear, I also installed new filters and brushed and skimmed profusely. Overall the pool looks pretty good except for what appears to be some sort of pinkish splotchy staining on the plaster, mostly on the sun shelf and some on the walls, I have no idea what this is or what it's from hoping you guys can help, need to figure out how to attach images, guess the file size is to large? Also I need to figure out some kind of vacuum system for debris on the bottom, but I'm trying to let my wallet recover a little after the pump fiasco before I buy a robot. Thanks in advance for any input.
