Been slamming pool. Its now clear and passes both chemical tests, brush 2-4 times a day. A couple hours after brushing, there again is debris on the seams. Is this dead algea? Which means i still have live algae on the vinyl liner? I have a sand filter.

If you passed the Overnight Chlorine Loss Test and the CC level is 0.5 or less (basically zero) then live algae should not be the issue. Seams certainly can trap pollen, dirt, etc and be a bit unsightly. Sand would feel obviously gritty. Have you been able to touch or exam the stuff you are seeing? Are you able to snap any good pics?
When you vacuum, I don’t think you’re really picking it up. it just disappears for a while and then settles back to the seams. I will see if I can snap a picture tonight.
Wind dirt, nearby vegetation, rain, people, dogs....
When vacuuming, make sure the pump is on high, filter reasonably clean - usually does not have to be freshly backwashed. All other skimmers/deep ends are closed (may have to keep one or more open a bit to avoid air in the pump). If your head has removable brushes, leave one in the front off to provide an easy path for the water to flow to the suction hole. Vacuum slowly to avoid kicking up dirt, and allowing it time to get sucked up. Do small patches at a time. Overlap strokes - one pass out, move the head 1/2 of its width for the stroke back, then over 1/2 width again for the next. You may have to linger over piles and jiggle the head back and forth over it to get it all sucked up.
I like the clear triangular heads for those reasons - add or subtract brushes to aid in suction (or scrubbing) as needed. Clear so you can see what is getting sucked in vs just being kicked up into suspension.
It may take me an hour or more to vac my 18x36 pool.
With TFP methods, moderate weather, and luck, that may be only every few weeks. Brushing much more often, of course. Let the amount of accumulation and how well it is being sucked up be your guide.

I have a similar issue with the seams in the deep end because the robot can’t get it perfectly clean. Looks good when done but I think it stirs up light sand/dirt then it settles in one area in the deep end. I’ve learned to just ignore it if it’s definitely light dirt. I’m not about to take out hose and manual vacuum just for these little spots.
Thank you for your information. Do you think it’s worth putting the diatomaceous earth in the sand filter to help with filtration?
