+1 on the automatic water changer (Python) suggestion. Even when I was laid up for 2 weeks with Bronchitis, I was able to keep up on water changes because all I had to do was hook up a hose to the shower, switch it on for suction, dose the tank, match water temp, swap to pump mode, then turn off when done. No lugging buckets around, you can sit in a chair and relax in between the brief moments you have to get up to swap the water direction. If you have someone there with you, this is a simple enough job that you can even dictate to them what to do while lying down/sitting and overseeing.
