So we have a large pool - 21x41. The return and skimmer is on one end of the pool. So the other end, there is never any water movement. So we were thinking about putting another return in on that side of the pool to keep the water moving.
I called one pool place and they said it would be at least $400-$500 to put it in. I called another to get another price, and they said that you cannot put one in, because it would compromise the integrity of the wall, and no manufacturer would ever recommend it.
1) go ahead and get it done
2) Try getting a bigger pump (I think we have a 1.5HP now) ***Correction - I went and looked - its a 2HP!!***
3) just let it go
Also - do I need to change the sand in my filter? It's never been changed, and it's about 4-5 years old, I guess?
