There is no downside at all. If you can hold a steady reading at this level stick with it. SWG mfg's like a higher stabilizer level than tablet pools because the tabs already have stabilizer in them. The chlorine from the SWG is unstabilized and is subject to be destroyed by direct sunlight quite rapidly during the swim season. I've seen plenty of pools with your level which were crystal clear and had no free chlorine reading. The chlorine introduced into the pool was gone just as quick as it hit the water. It was doing it's job as sanitizer but left no residual reading.

The only downside is that the cell may not last as long. Typicall cell life is 15,000 hours. The more it runs the faster it is depleted.

Personally I like to keep the CYA ~50ppm the chlorine tends to be far more effective (measured in orp) at this level.

Similar to how ozone functions. It will detroy the bacteria that it comes in contact with, but leaves you no buffer for when more bacteria is introduced.
