Intex 18 x 9 x 52 ultra frame rectangular. I just got new baracuda ranger above ground pool vacuum. it wont run. ( runs for like 30 seconds) keep slowing my pump to the point of erroring out my SWG which gets an error saying low flow from pump. Any sugestions? the ranget doesnt have specs to say wether my pump is big enough to run it. I have 1200 intex sand filter pump.
