I just posted a pump issue, but thought it was best to post this one seperately. Our pool was installed yesterday. We have the filter running and the return jet in the pool is aimed away from the skimmer but we think is aimed too high because we can see lots of bubbles on top of the water- we hear the water jetting in and we see the water jetting in. We have tried moving the 'eye' but it doesn't move. We believe it is aimed in the right direction but too high. How do we lower it so it returns the water lower into the pool. Thank you.
