ok, im going off to college in a few years, and I want to make sure that my arowana can get his water changes, but my parents may no longer be physically capable of doing them. Even now, it is a problem. I NEED to get one installed ASAP. Every week, my dad is grumbling as he helps me take buckets of steaming hot water (we dont have hot water in our basement) and drags them down the stairs. I dont want my aro to lose his water changes, he'll die. so, HOW do you install an automatic water change system? price is no object. it NEEDS to be done, so ill raise every last penny myself if I have to. he should get a 50% every week.
