I plan to get a 10 lb cylinder for my 29 gal tank but not sure what to do when it's time for a refill. With the co2 supply so drastically interupted, I worry about causing an algae bloom. Would simply turning off the lights be enough? Not anxious to buy a second cylinder to fill in while the 10 lb is refilled.
