Hello Whistling. I gave up the buckets years ago. Finally, I got too old to do all that lifting. I went to the Python to drain the water and then got a faucet attachment to fill it. I can do the 300 gallon tank in roughly 45 minutes.I think if I ever get a tank this big, I'd just go all the way and run plumbing to it. I sure as heck would not be doing those water changes with buckets. I'm tough but not crazy!
