So, I'm out of town a lot for work and bought two auto-feeders for my tanks because my fiancee doesn't have the best memory. The one is the eheim double feeder, which you just lift the flaps and refill. The other is the cheaper rotating drum type with a slider to adjust the opening. My fiancee noticed the double was getting low so she refilled it. She thought, since that one is getting low, better check the other as well. Nice thought, but she had no idea how to fill it. So she tears off the slider and fills the drum, but then can't get the slider back in. So I come home last night (two days after she refilled) and the entire drum of pellets is in the water. It looks like mud in a cement mixer. I've done two 50% water changes with the gravel vac and washed the filter every three hours. The fish don't seem stressed anymore, and they would get eaten in the bigger tank, so I don't think it's worth it to move them. Is there a maximum on how many water changes I can do in a given amount of time? I match the temp and ph each time and dose with prime.
