I'm afraid I've done some damage. Warning beginner learning the ropes and terminology.
I have two skimmers one in the deep and one in the shallow end which each have valve shutoffs.
I went to vacuum the pool by hooking up the vacuum hose to the skimmer inlet and running the telescoping pole along with a simple weighted vacuum head. This was while shutting off the deep end skimmer and just sucking with the shallow end skimmer. I had great suction at first and then I noticed I wasn't collecting anything more. I found that I clogged the skimmer line. I shut the shallow line and let the pool just run with the deep end skimmer and all was well (aside from the clogged shallow end). I went out the next day and heard the pump running noisily and found I had no pressure. I turned off the pump and attempted to clear the clog with my shop vac. With the deep end shut off I can see that some water is making it to the pump put not enough to pressurize the filter. Having both the shallow and the deep end does the same. It seems to start filling up but then drops a bit and is never able to fill up the pump.
What have I done to my poor pool?
I haven't had the pump run for a few days as a result. Should I be dumping in bleach to prevent the pool from growing algae? The pool is already a green mess with loads of debris at the bottom. Sandy put a hole in the cover and let a nice amount of leaves and sticks in. I'm also looking to get an automatic cleaner but I'll probably start a new thread for that after further research.
Thanks in advance,
