Soft Scrub using a Scotch-Brite abrasive pad. It removes those black lines great. I have a 20 X 40 in-ground pool & I clean the pool line every spring. Soft Scrub works great and does not mess up the chemicals in the pool. Hope this helps.

Can concrete set under water?
Yes. Water is actually needed for concrete to set and is vital to the curing process. Concrete will set just fine under water. Depending on your specific application (will all of the pour be under water or will it start under water and finish above the water line) you may need to adjust the initial dryness of the mix as well as take more care in the pour. All of the volume of the concrete that is under water shoudl be poured in continuous fashtion. If you must pour in steps, the start of the next pour must be "in" the old pour so as to not leave a water survice between the pours. This "seam" will tend to stay and produce a weaker stucture.
