Right now I have 9 tanks up (yes 9 individual tanks).
Of those 4 are hospital/temporary tanks (3 of my 4 rescues and one as a hospital). The others are my normal tanks.
Normally I spread water changes out over a week. For instance I'll do my divided 10 gallon and my 4 gallon on Sunday. Monday I'll do my 2.5,3, and 6 gallon tanks. Then thursday night I'll do the 2.5, 3, and 6 again (I do 2x weekly on those tanks). Since my four gallon is planted I only do one weekly change on it. It takes me about an hour to 90mins to do water changes.. sometimes more if I take breaks inbetween.
Now that I have extra tanks I'm doing water changes every other day (100% for the 4 small tanks). To do the small tanks it takes me about 30 mins since all I do is dump out the old water and throw in the new. Once a week I rinse all the tanks and plants.
This week I was really bad. I didn't do any water changes so I'm having to do all of them in one night. To do all 9 tanks is probably gonna take me about 3 hours. Since I take my fish out to do water changes I have to wait for cups to become available so it takes a while.
So whats your water change schedule like? Do you spread them out or do them all at one time?
I'm curious about people like me with LOTS of fish (its hard to believe I have 12 now
). How do you handle multiple tanks and water changes?
