Whether or not failure to do so will cause an algae outbreak, I can't recall. To gas-off a pool you do need to remove the solar, or retract an auto cover for an hour or so a day. If you didn't do this for a few days at a time, it could be the reason for the "solar cover/algae corelation". I'm sure someone else here can tell you the process better.
Thanks. I'm sure there is some correlation, and you may be on target! Need to get a reel, but for 24' pools, they aren't cheap!
