I can hear the gas line hissing from here uxbridgechris. I didn't cover this year and will open the system on Monday. I've skimmed out all the Crud and dumped in the first round of chlorine with sub-pump circulating. Will run robot vac a few times tomorrow while scrubbing and managing chlorine level. We've got a hot tub so we'll likely be going hot-cold-hot until we really want the whole pool.
