I'm scheduled for a 5 weeks vacation in May. I wonder what are the water change options I have for my discus. Having someone over to change water for me is not an option. There are so many things can go wrong and I just don't see it happen.

That said, I'm thinking of two possible options:
1. Condition my Discus for less water changes. I'm doing 40% water change every 5 days. I can slowly increase the days to one week, then two weeks, then three weeks before May. Maybe this way the two extra weeks are not going to be too hard on them.

2. Another option is keep doing the 40% water change till one week before vacation. Then doing 30% water change everyday righ till one day before I leave. That way the water is going to be really fresh. Maybe that will help them to pass the 5 weeks.

Any advise?

I'm going to use an auto feeder with some flake food. It willl feed the fish twice a day and they are used to eat some flakes. I used this before for my other fish without any problem for 5 weeks. Never tried on Discus.

My current set up:
125 g tank with a Fluval 304 and a 404.
11 3" Discus
3-4 small cories
3 small ottos
PH 7.2
Temp 88
Lightly planted
Some driftwoods
