help!! fish dying...my coraline has turned white

You haven't clarified how new this system is

I suggest you read up on the nitrogen cycle on the web so you have a better understanding what's going on. You've led me to believe you don't understand it with your initial comment about having .5 ammonia

So ... I should have been a bit clearer with my comment about your ammonia
0.5 isn't bad but it's getting there. It just means that you are going through a cycle. This can happen any time you transfer stuff between tanks.

You should initially test for all 3 and keep note of the results
Ammonia NH3
Nitrites NO2
Nitrates NO3

Keep an eye on your NH3 and if it goes over, say, 1.0, do a 10 or 20% waterchange. And test your ammo more than once a day.
Don't change more than 75% water over a 24 hour period !!!

Keep an eye on your ammonia and, when it drops and goes away, then your NO2 will be most likely in the mid-point of it's cycle. Eventually your NO3 will take over and you're finished with the initial worrying.
As I stated at first, read up and understand what's going on !!!!!!


You should also be adding some air to your tank right now as the oxygen is probably low. Either an air pump, or some kind of surface agitation with the top open to the room. I'm not saying expose jumping fish, but you have to let the surface air exchange happen

Try adding some Prime to the system. It's supposed to detoxify ammonia and nitrite

Sure, Prime works great in a pinch, but what about knowing what's going on and learning how to deal with it ??

Absolutely, but right now they need something that works in a pinch

How long ago did you replace the seal and what type of silicone did you use?

Good point Steve ....
I missed this completely

[BlueWorldAquatic]

Did you move the sand over?

I would recommend Stability help stabalize the bacterias, and AmQuel Plus for the Ammonia (we actually tested prime & AmQuel, and found AmQuel much superior for removing Ammonia Nitrates Nitrites Chlorine & Chloramines)

Silicone can be the issue also, depending if it was mildew resistant

You're absolutely right
Sorry for coming across the wrong way

I only meant to point out that, once they get things under control, they should read up on how to properly deal with things
