Pool water clear, chems test fine, have to vac daily and still get green/yellow 'dirt' covering the bottom.?

Question

I'm admittedly a pool rookie, this is the first full season we've had our pool I've been battling this for weeks now. Our water is perfectly clear and the chemicals test at ideal levels. But, I cannot get rid of this yellow/green dirt at the bottom of the pool. I have stretched a section of panty-hose over the skimmer basket and put a white cotton tube sock in the basket too. When I vac both have this gross yellow/green tint to them that I keep rinsing out. The stuff settles in the dips in the liner and looks like dirt from above. We have corn that's tasseled nearby and also a walnut tree, I've heard they might be the cause.

Answer 1

I have had several friends with pools have this same problem.  I think that the particles that are in the water are too small for the filter to capture.  My thought is that it is pollen but I'm not positive.  Try back washing the system completely.  If you have a sand filter you might need to replace the sand.  This didn't seem like a normal solution to me but my brothers pool company told him to do this and it solved his problems.  If you have a filter that uses Diatomacious Earth, completely backwash the system and replace the DE.  God luck!!

Answer 2

It is pollen.  When the season for those plants to pollinate has past you will be free of that residue.  

Depending on what kind of filter you have, you may have to clean it out after the bloom is over.

Answer 3

/agree w/ top.  Do you have trees around the pool?  

What about evergreens in the neighborhood?  Tree pollen can travel a long way, and just like it can coat a car, it can coat a pool, though this time of year, it's usually all gone (depending on where you live I guess.)

Answer 4

it's probably pollen  

Answer 5

If the chemical tests come back clean dont worry about it - it is probably just pollen. Nothing to worry about. I dont know how you can get rid of it, if it is aesthetically displeasing for you. Perhaps your local pool store might have some ideas.

Answer 6

IS THIS YELLOW GREEN DIRT CLOSE TO WHERE THE WATER RETURNS TO THE POOL, LIKE AT THE RETURN JETS?

IF SO AND YOU HAVE  A D. E. FILTER OR SAND FILTER THAN YOU MIGHT HAVE  1 OR MORE HOLES IN YOUR FILTER GRIIDS LETTING D. E. POWDER RETURN BACK TO THE POOL.OR IF IT IS SAND, YOU MIGHT HAVE A HOLE IN THE LATERALS OF YOUR FILTER. IF SO THEN YOU WILL HAVE TO REPLACE THESE PARTS ! IT IS ALMOST IMPOSSIBLE TO VACUUM THE STUFF OFF OF  THE BOTTOM OF THE POOL SINCE IT IS SO SMALL IT JUST GOES STRAIGHT THROUGH THE SOCK.

Answer 7

We had a similar problem and finally found a way to solve it - Go to the store and get the basket "socks" that are made for pools (they are more dense than nylons or normal socks) and put 2 of them (one over the other) on the filter basket and vacuum (very) slowly and thoroughly.

This should remove the majority of the pollen/dead algae that you are seeing - You may need to do it for a few days to get it completely cleaned up.

The problem is that the residue is so fine it passes through your sand filter and is returned to the pool even as you are vacuuming - once the water settles you see that it didn't go anywhere. The socks work great for getting the fine particles out once and for all.

Answer 8

that is pollen and as long as trees bushes and shrubs are pollinating you will not get rid of this just keep your chemicals up.i deal with this every day pool company owner
