So it's getting close to the time to close my pool. This is the first year I used a stenner pump to administer the chlorine and it worked so much better than expected. My plumbing to my pool is outside my garage wall so I installed the pump on the inside wall with a 15 gal. tank under it and run the feeder tube through the wall. It really works great. My question is that after I close the pool, I will have 5 or so gal. of chlorine left over. Will it keep if I leave it in my tank or should I put it back in the 5 gal container I bought it in. I buy 12.5% liquid chlorine in 5 gal. containers ($16) from my local pool dealer. It's actually cheaper than buying gal. jugs from Walmart. My garage stays above 40 during the winter months here in NY.
