First off, this is a great site! I'm completely impressed with this forum. This post is a bit long, but as with pools, please be patient with me. I recently purchased a house that has a salt water pool installed in 2006. The pool was green and needed help. I have since cleaned up the pool as its blue, but still a bit cloudy. I had to manually shock the pool and it does not seem like the SWG can keep up with the demands of the pool.
My issue is with my Zodiac LM2-24 SWG. It will not go above the lowest setting on the output. That's 1/5. The low salt light is on even though my salt content is at 4300 ppm (Zodiac recommends 4000+). The previous owner said that it never could keep up and was told that it is because the SWG is a good 40 yards from the pool. The low flow light does not come on, although it flickers a bit when I tried the superchlorinate option. The manual is most unhelpful, but does suggest that it may be because of low main voltage.
The piping on the pool is 1 1/2 inch with a 1.5HP pump and sand filter with a clean pressure of 18psi. The approx distances that the water needs to flow is:
inlet to pump/filter = ~20 yards
pump to heater/SWG = ~60 yards
SWG to outlet = ~40 yards
The outlets seem to have some pretty good flow and the low flow light is not on, so I'm not sure I believe the previous owner that it is the distance that is the issue.
I called Zodiac and someone is supposed to come, but never has. I called when I was having trouble turning the unit on or off during backflush and at a point only the superchlorinate option would work.
Am I missing something.
Here is my current water balance:
I will likely increase the CYA to about 60 over the next week, but would really like to know how to make the output higher than the lowest setting.
