A big thanks to this community as you have helped me with many issues.
First summer with a pool and it's been trouble free (until now).. The pool liner continuously has a green film in parts of the pool (and seems to be getting a bit out of control). I am having to run the Dolphin robot 1-2 times daily and it doesn't seem to keep up. This was not the case in the summer as I went all summer without issues and was running filter about 8 hours a day and the dolphin cleaner maybe once every day or so.
The fall is coming quickly as we are getting cooler temps here in Illinois early this year. Along with this comes a bit of additional debris in the pool. I can only assume this is causing the liner discoloration?
I am currently running my filter 8+ hours a day. In fact, it's probably closer to 10+ due to the additional debris. I have the SWG running and the FC levels are usually around 4-5.
Also note, that I have not had a working pool cover all year--but am scheduled to get it repaired soon.
I've never used an algaecide.. Is it time for me to do so? Any other advice? Should I be concerned or is this something that will happen every fall?
I've been having a tough time keeping Ph at or below 7.8 lately.
