Circulation issue, ideas for better return fitting

[canjones]

I previously posted about a circulation issue with my pool and I am still battling the issue. One return line, 2 ft from skimmer. My pool is fairly large, partially inground, depth is 4ft around and slopes to 6ft in the deep in. I purchased an Infusion V-fitting which circulated about 2/3 of the pool. Dirt and debris settled to the bottom of the remaining 1/3 of the pool which means I still had to brush every day! I have concluded that the pool is too large for one return line. I just purchased the Polaris 65 because we had that before from the previous home owners and it worked for a moment until it conveniently broke after a month of living in the home. I think the Polaris will at least help keep things circulated and pick up all the leaves. I also know that we need to cut or trim back the very mature trees (yard backs up to the creek).

Is there anything else you think I could Do? Perhaps something homemade? Someone mentioned attaching an elbow to the return line but I really don't know how to go about doing that.

It was also suggested to try the circulator but I just really feel that it still won't help circulation in the other end of the pool and I'm not willing to pay $60+ to find out.

Why do you "have" to brush everyday? I often leave dirt and debris on the bottom of my pool for several days and throw in the cleaner before the weekend.

Is it just the debris that is of concern or the actual water circulation (i.e chemical distribution)?

It is a very rare pool that doesn't collect dirt on the floor. That is why they invented floor cleaners. I doubt there is much you can do at this point to prevent dirt from reaching the floor except maybe add another return. But some dirt will still settle on the pool floor.

It seems that when I leave dirt and leaves in the pool my problems get worse as the days go by even with checking my FC everyday. It will always read some level of CC when I leave stuff in the pool and the walls of the pool and ladder will show green. I think the bleach is getting circulated. I take a sample at the farthest end away from the return line. I use the Pool Blaster vacuum which does a good job of picking things up. But pretty soon the leaves are going to start falling like crazy and I won't be able to keep up with it.

Sounds more like a chemistry issue than debris issue. Moving the debris from the floor to the skimmer and/or filter doesn't really change anything other than aesthetics. Pool water continues to flow over the debris when it resides in either place. But it shouldn't matter anyway since the chlorine kills any algae and bacteria fairly quickly. Having the debris sit in the pool shouldn't add much to the chlorine demand because everything is dead (assuming correct FC levels).

What is the pool FC level and CYA level targets? Do you even allow FC to drop even accidentally?

CYA 30, I try to keep my FC between a 7-9 because I have so many problems.

It didn't read through all your old threads but have you completed a SLAM as described in Pool School?

If you have and that is dead algae, you may need to add some DE to the filter to be able to remove it. Otherwise, the sand filter may not capture it. Is this what you are still getting:

 

[canjones]

Yes, all the time even after SLAM.

 

[mas985]

So have you tried the DE in the filter?

 

[canjones]

No I haven't. There's a link for instructions on that right?

 

[mas985]

Just add enough DE through the skimmer to raise PSI by 1-2. Then try vacuuming up the debris.
