im new to pool stuff, this will be my first year actually setting up the saltwater system. My pool was pretty cloudy after i got my new system. i took a water sample in and i had sum algea, ph issues and calcium issues, plus no chlorine.. so i shocked my pool yesterday becaue my new filteration system hasnt been working more than 48 hours and hasnt made any chlorine for the pool yet. so after i had added the shock i went to vacumm it today and after about 10minutes i got a low flow light.. Im really not sure how to fix this.. i closed both plunger valves and drained the water from the basket.. cleaned out the basket and restarted everything. the beeping sound for the low flow is still on after turning it back on.. so i than did a backwash on the sand filter than a rinse.. turned it off and when i turned it on it still had a low flow.... HELP..
