Today they acid washed the pebbletec. Before they did that though, they pulled the wires for the light. They connected the wires to the light but set it up on the Kool-deck. That is so - when they pour the acid on the pool it does not get into the light. Then they put the acid into a water can with a little bit of water - then poured it around the edge of the pool. The other worker had the water hose and sprayed it down. They did the whole pool that way.
Then one worker took a power washer and sprayed the pool again. The other put in the jets.
When that was done they put in my light :) !
