Old pool - pool circulation

I bought a house with a Fiberglass pool from 1968. The surface has been refinished and visually looks great. I am using the BBB method and the water is sparkling clear also. However, I struggle with dismal circulation issues. It does a terrible job of moving leaves to the skimmer and the only way to get the fine dirt particles out is for me to manually vacuum (big hassle). I have a plug in electric robot vacuum that does great but the finer particles seem to swirl too much to be caught well. This old pool has had the main drain cut off and disconnected (according to a pool cleaning company) and therefore does not allow me to sweep particles to it for capture. There is 1 skimmer at the end and only 1 return jet at the opposite end. There are also 2 jacuzzi bubble jets at the return end but we never use them because there is no heater and it‘s just part of the pool. (See picture for visual reference).

So my issue is that with only 1 return jet I cannot get enough circulation to really push the debri to the skimmer, the debri all piles up on the steps because I can‘t point the return towards them without neglecting the rest of the pool, and the water turnover takes forever while leaving many dead spots throughtout the pool.

I have thought about trying the rotating return jet that I’ve seen on the market, but it didn’t get very good reviews. I have also considered seeing if there is a way to convert the bubble jets to be additional return jets instead - at least that would give me three directional options. And lastly I have considered seeing if the main drain can somehow be re-connected. Is that even possible? This kind of thing sounds very expensive when I am not even sure any of it would work. So I need some advice. Have any of you had to deal with an old fiberglass pool with only a single return jet? What options do I have? I am open to all ideas. Thanks in advance!

Which direction are the pevailing winds?

Prevailing winds are more powerful then return flow for moving surface debris. The debris will accumulate in the areas the winds push it to.

Being on the lake here the winds are certainly a factor. But the direction is very seasonal. A little over half the year is from the East (from return towards the skimmer) and the other half switches and pushes everything away from the skimmer. But if I point my single return jet to push the debri towards the skimmer, then the lower water, steps and corner all have very stagnant water.
 
Research a skimming robot. Many on the forum have luck with that.
Circulation is not as big a deal for water chemistry as you think. Maintaining proper FC to CYA ratio is far more important.
What robot do you have?

What makes you think the water is stagnant?

Brush your pool every few days and it will mix the water around.

Perhaps stagnant was too harsh of a word choice. But it is clear that debri remains very still all day long in certain areas if i’m not quick to get the vacuum in every day and it can take a great many hours for chemicals to fully disperse.
I’m spending a lot of time maintaining my pool, so I’m trying to get it tuned up as much as possible so I can spend more time enjoying and less time cleaning everyday.

One return and one skimmer with no main drain will do that.

Improving your pool circulation will require more than a tune up.
 
Perhaps consider a robot (filters, cleans floor and walls, and mixes your water immensley) - I have a pool that pulls in lots of debris, but between two skimmers and a Pentair Warrior SE, I do very little work other than this time of year (leaf-mageddon.)
 
I wonder whether there's a way to convert the bubble jets to normal returns. Is there an air intake you can plug? How are the jets plumbed compared to the regular return?

They make robots specific for skimming. Battery powered. Independent of your cleaning robot.
Do a search of the forum.

I have a Polaris IQ that does a great job with the bottom and sides but no help with skimming.
As the others recommend a solar skimmer will keep your surface cleaner than even a great working pool skimmer. I have just recently purchased the Betta 2 and am very impressed at how clean it keeps the surface and allows me to keep my pump run time to a minimum. Be sure to read the posted link above as well as this one..

The bubble jets have a pipe sticking out of the ground that sucks in air when turned on. They are on a separate valve from the return jet. So somehow the water between the filter and the return jet would have to connect to the bubblers. Does that sound possible?

Post pics of your equipment pad and valves. Especially on the return side.

I am looking into the solar skimming robots to add to my vacuum robot routine. Thanks everyone.
And here is a picture of my very old equipment. Old but still working fine for now. You can see the air intake pipe for the bubblers on the right.

There is no reason not to run both return valves open and let water flow out of your one return and the bubblers. You can put a piece of tape or a cap over the air intake to stop the bubbles and let smooth water come out of the "bubbler" returns.
 
Blocking the air intake will cause no damage. Those pipes will operate as normal returns.

Determine the pipe size for the air intake.
Purchase a 6" or longer threaded nipple and a screw on cap this size.
Cut the threads off one end of the nipple.
Screw the cap on the threaded end of the nipple (don't over tighten).
Glue the non-threaded end of the nipple into the 90 on the air intake.
This will provide the option to allow/disallow air into the pipe.
