Hey all. New pool owner here. Long story short - last night I had the water circulating in the spa only. I turned off the pump, switched my return line back to the pool only in prep for the morning cycle...and never switched my suction side. Came home at 5 pm to an empty spa. Its a brand new pool, today marks 3 weeks with water in it...it's pebble tec. I know my chemistry is gonna be all jacked up now. I'll try my best to get that under control tomorrow. Any other concerns that I should know about? Have I caused any damage to the pebble tec? Everything looks fine...pump is running fine now. Just seeking some input.
