Have you tested the water? Was the acid level within normal? If it's too high, lowering the acid will probably get rid of the smell.

If you have enough acid in a swimming pool to smell it, I wouldn't let pets or children near it!I hope your smelling chloramines, spent chlorine molecules. Take some water to a pool store that does free test. Their test equipment should be more accurate than your home test kit. If your "off the charts" it can effect the test results.
Follow the instuctions. Re-test after 24 hrs with your home test kit.
If your getting algae problems you might think about a product like phosfree or no mor problems. They seem to help.
Good Luck

The first thing is to get an accurate test of your water. If you have a Leslie pool supply near you they will test it free. If you have no one locally then you need a test kit to check your levels. You have to get the water balanced first. If the acid level is high (ph=low) then that can be corrected. If the chlorine level is high, that will dissipate with time and exposure to sunlight. Make sure your pump is running at least 5-6 hours a day. As mentioned above, if your pool is prone to algae, you may have a high phosphate level. Phosphates are like food to Algae. Again, the key is to get an accurate test and then make adjustments based on the volume of your pool.

Thanks everyone for the help! I ended up draining the pool and refilling to get rid of that smell and it worked. This whole thing started with a stupid green algae bloom. I have had the pool for 6 years and have never had a spec of algae and my chem's were always perfect. We had a string of days that were stormy, rainy, and cool so I left the solar blanket on to keep the water clean as I always have done in the past. Never had a problem, but this year I bought a new CLEAR solar blanket and it let in way more sunlight than the standard blue ones do. When I took the cover off the water was crystal clear but the bottom was covered in what looked like just plain old dirt. I put my Robo Klean in and all heck broke loose. The water turned green and cloudy so I started shocking/vacuming/backwashing/repeat 3 times a day for 4 days. The water finally cleared enough to see the bottom again but was still a little cloudy and the water just looked off. The PH/chlorine/free chlorine/alkalinity/ cya was so high it turned the stick every shade of purple there is and one color I don't think exsisted until last Thursday! My drops test kit was no help so I took a sample of the water to the pool store and the guy just shook his head and said the water was so messed up he couldn't offer any advise on how to fix it. I went to another pool store and the guy suggested acid to bring the PH down and clear up the water. So I added acid per instructions to bring the Ph down and that is how I got the awful smell. Could the smell have been chlorine? Even with all the shock I was pouring in the pool I didn't notice any smell until I added the acid. Well anyway. Lesson learned. Bought another solar cover. Plain blue, thank you!
