Hi! We have a 18x36 rectangular pool. Roughly 26,500 gallon pool. Did a reno in Feb this year. Also had pool deck redone with new concrete.
We live in a semi rural area and have a cistern for water which is collected from roof (all run through filters and uv system). However pool water was trucked in by water hauler.
There was quite a bit of debris/dust etc on the white fiberglas steps that I planned on cleaning before the liner went it. I believe the concrete crew cleaned up what they could but not to the level I would have done. Once pool was filled it was easy to see there rusty pin head spots on the steps. Worse were opposite the return. No one seem to know what caused it or how to address it. I had multiple suggestions. Vitamin c did nothing. Pool builder had me speak to a pool store owner and had me use UC Pool stain Treat. I put it in a skimmer sock and left it for a bit on the spots. Which worked well but got tired of messing with it figured I will address the remaining spots when i open the pool next year.
Fast forward to mid may started seeing small bits of algae on the wall near skimmer and a spot on the floor. Pool builder had told me to use trichlor (in line feeder with flow adjustment) to regulate how much chlorine (and CYA) went to the pool. I had on the lowest setting and once I felt cya was at a manageable level I took the tabs out. I should be around 40ppm. Tablets has been removed for about 2weeks. Then use a gallong of LC once a week and O would be good. Prior to finding this forum I had been using strips, then purchased one of taylor kits.
Anyhow bc of the algae and finding this forum I started a slam on June 17th. 18th was my first full day. I checking levels every few hours on my last test at 3:30 I add LC and was getting ready to brush the pool and noticed purple on our grey drain color. Shut the pump down and took a picture. To get a closer look. Does anyone have an idea what would cause that?
