I bought a 35 gallon trash can and I can add water to it run for more fill it then mix then pump it in the tank for water changes

I only use it for clean freshly made water....but it sure helps when I do massive water changes on my 125.

The rubbermaid can cost me 14 bucks? I keep it out in the garage laundry room or whatever until I need it.

The only issue is trying to keep everyone from using this as a trashcan.

You can get wheels for this too and store water in it short term.

My husband brings me 5 gallons at a time...so this is VERY helpful for us.
