So I have noticed a lot of discussion lately on water changes..
Thought I'd show you all how I do a 25-30 gal water change on my 125 gal tank...
first pic is just the tank..
The 2nd pic shows the 2 inlet pipes bringing in fresh tap, and filtered RO water, and the plumbing. The green valve stops water from returning to the tank, and the 2 red valves are fill, and drain, the drain is on the bottom...
So I close the green valve, and open the drain valve. Now the filter pumps water from the tank into the house drain in the basement.
the last pic shows the water level down about 6 inches. 30 gallons or so..
