So as everyone knows, the holiday season is here. I will be away from home for a month or so and was wondering how long I can go without changing the water? I have a home made manual feeder (Internet connected feeder, I can trigger it with a text message or a click of a button ) so that's not an issue. I have precautions in place to keep it from jamming, dumping too much in, etc. Also have a second feeder thats connected to a Internet connected power strip, so if the main one fails I can turn the secondary on. Tank is fully cycled (0 ammonia, 0 nitrite, 15 nitrate), all the fish area healthy, active, and colorful. They get fed (by hand) twice a day--before work @ 8:30am, and after at 6:30pm (and a algae pellet at 11pm, right before lights out). I decided to avoid changing the water to see if it would affect the fish or water in any way, it's been about 3 weeks and the water tests fine and the fish look as they did a week after I got them (they started looking MUCH better than they did in the crowded tanks at the LFS).
