i had the same problems and most fish died, salt and temp didn't work and sand caused the ich. My sand had massive tiny worms and i was unable to clean them. maybe a better filter and definantly remove the sand.iManipulate;3465604; said:I know it's overstocked. We got all the fish when they were super tiny. He will be upgrading soon, no worries.
I didn't get to check the levels yet, I'm going to do that today.
Yes, there is carbon in the filter.
I figured we'd have to do a huge water change. He has sand as a substrate in his aquarium, could this also be affecting it?
