Best way to do a water change in a small tank?

[Arklier]

Going to do an approximately 20% water change in my 3 gallon soon. What's the best way to do a water change without blowing the substrate everywhere?

[reefnoobs]

in a tank that small i would just use a cup.

u could try pouring the water over a bowl to help spread out the flow...i've done that

[epracmetcon]

I just pour mine into my HOB.

I second the cup and HOB method.

I third.

jus use siphon to remove and siphon to add (small airline tubing works fine)

Thats what I do on my 1.6G... Slow in, Slow out with flexible airline tubing.

I just use a cup to take out & to replace

small gravel vac to suck out and then I use a cup to pour back in.

 

I do about a 2 liter every week on my 3 gallon.

I know this sucks as as a first post to be resurrecting a kind of old post, but I just wanted to share how I do water changes on my 1 gal tank.

 

I use a turkey baster. You dont need to siphon, and the flow of water is controllable. It works well for me, but I dont think it will work well for tanks larger than 5 gallons because to take out 10-20% of the water will require you to do a lot of passes with it.

Just pick the tank up and tilt it sideways until the water starts pouring out.
