I wish I could say I love cleaning the tanks but I do it anyway. It wouldn't be a problem if I didn't have rheumatoid arthritis. I only have 2 tanks - a 10 gallon and a 20 gallon - but moving the water cause a lot of pain and I can't do them both on the same day. I use gallon jugs to transport the water from the sink to the tanks and also use gallon jugs for the dirty water which I use to water outdoor plants. One time I did them both on the same day and couldn't use my right arm for a week after that so I won't be doing that again any time soon. It's the moving and lifting the jugs that causes the problem with my shoulders. I end up moving the full jugs a lot of times each.
