Hello everyone! I have a question I am needing help on. I have a 200 Gallon Fresh Water tank and curious how most people with a tank that bid do water changes. I have the large Python Siphon with the faucet pump. Do I need to fill water in buckets with the dechlorine additive, or can I just fill the tank straight from the faucet and then add the dechlorine additive to the tank?
