A dying question?

Ok so something did not sound correct to me about the flow for my powerhead and there is, it is actually a 1600 G/H powerhead not 1600L/H.

First off very sorry to hear about the crash. I too am fairly new to this and the learning curve is harsh.
What others have said about the cycle taking much longer that expected is so true. My nano is so much easier to take care of now than it was 6 months ago. I have added/removed nothing in that time( except water) it just keeps getting more and more stable.
One thing nobody has talked about yet is surface agitation. By using a canister filter you have limited gas exchange in your fitration system so it increases the importance of having the surface of your tank turning over to get oxygen mixed throughout your entire water volume.If your pump and power head both are not causing ripples on the surface of your tank this could have made oxygen levels lower than expected and add another factor into this problem.Just an idea from one newb to another.
Good luck getting things going again

Yes my powerhead generates lots of waves I even had to move it lower into my tank for I use to have a world pool that was sucking up air
