Water change day

Indeed - Before my water change system, I drained tanks into a rolling trashcan with a 1 1/4" hose (available at Home Depot). Trashcan pumped out to the yard.

You can greatly speed up the drainage process with a larger diameter hose and or multiple drain hoses. Swim pool hose is popular. Could also use pump on hose, choose a soft solids pump.

I installed a wider diameter water supply pipe to my fish room. Doubling the diameter had quadrupled the flow.

The python system is a game changer! I have one and I can do a 80% we on a 125g in 30-45 minutes. Also I never have problems getting the water to temp. As long as the water you are pumping in is close the water in the tank will balance it out. I dont stress about that the thing that stresses me out is I can never take my eyes off of my oscars lol they like to bite my arm and hands when I’m doing WCs

I always kept oscars when i was younger. Definitely looked at them as a "water dog". Almost like how a dog will wag its tail and come running over to you when you come home.

I am amazed at how long peoples water changes take.
I had 20 tanks on 5 sumps, total 1500-2000 gallons, but used a semi-permanent 2" PVC line connecting all sumps together, and running old water to my garden.
When I opened the valve to that 2" line, in stead of water going to the sumps, water flowed by gravity to the garden.
A water change on all 20 tanks, would take no longer than 15 minutes to send old water to the garden, and another 15 minutes to replace with new water.
If I was pressed for time, I might isolate 2 sumps for change and cut time to 5 minutes, on about 500 gallons of tanks.


Of course in winter water was sent to toilets instead.
