python. If you need any special adapters (although i think most pythons and similar products have ones you need) you can go to the hardware store and get a waterbed adapter or something
I had a python before even though they had a adapter that was supposed to fit onto your kitchen, bathroom faucets those somehow didn't work for me. When comes to the utility sink in basement it fitted fine.
I had a drain and hot and cold water lines put in the wall behind my 210. When I do water changes, I just put the end of the siphon in the drain to take water out. To fill up I turn the water on and this fills my sump which fills the tank.
I like the Aqueon brand water changer more than the python. The plastic is better quality and the valve design is much better IMO. The python attachment that goes on the sink faucet needs to be twisted to "close" it to fill the tank... Usually gets your hand wet and is just kind of stupid. Aqueon has a switch up by the faucet you just flip.
you have 3,000 posts on MFK and you are STILL using buckets to fill your tanks all I have to say is WWWWWWOOOOOOOOOOWWWWWWW. You have got some serious dedication and probably some strong arms
