Aquarium Advice FINatic
It could have been some really fine particles that were in your sand.
What inverts are you thinking about getting? You could feed them a small amount of pellets or pieces of krill.
I'm not sure if you can keep a banded and sexy together, my banded will eat ANYTHING. You'll have to check into that, wouldn't want anybody getting munched on.
0 nitrate? Your nitrate levels should be very high at the end of the cycle
Nitrate levels don't drop on their own, you have to lower them through large wcs
To get from 160 to 10 ppm you would of had to change out ~90% of the water
Retest your water if nitrates are still showing 0 take water to your lfs to get it tested, if you have a false low reading and they really are high anything you buy will most likely not survive in your tank.
