Help, please.

A friend of mine has a tank with nitrates out of control.
It is a 10g tank that is down to having just a painted glass fish (big no no, yes we know), a leopard danio and a large apple snail.

The fish have been dying and the nitrates are the problem from what I can tell. It's very high (gaah! I can't remember the number but it was in the center of the unsafe range on the chart).

Anyway, I did a 50% water change and the amount went down slightly but not enough.

I would like suggestions on firstly how to get the nitrates under control and also what to add to this tank (plants, rocks, etc) to make the remaining fish happy.

Thanks. I plan to go pick up supplies VERY shortly so any help you can give would be greatly appreciated.

Sure you mean nitrates and not nitrite, a nitrate above 050 wan't fetching down by water changes, once water quality is good maybe some more danio's can't be on his own.

100% positive it's nitrAtes.

Just water changes then, check filter sponges to see if they need a slight rinse in old tank water, and maintain filter by cleaning it to get it back to full speed, good luck.
