I have a five gallon bucket, use it to take out, and use it to fill. no big deal here. But of couse it does get tiring with a 55 gallon or bigger oh well ,my 29 only take a few bucket changes every week, no biggie to me.
I use a 24 gallon tote to let water sit and chemicals disapate, then I have a bait aerator I purchased from walmart along with clear vynil tubing purchased at local hardware store. Bilge pump will work to but u need a dc power source.
