Tank cycle

Hi,

Recently moved my tank about 2 months ago to a new house. System was fine before move.
Once moved, and moved quickly, my bio system seemed to go down. Now 2 months later and it won't kick in. Ammonia lvls are up around 10ppm which is very high, I have not done a water change for 2 weeks now trying to get the bio going.
Had a few fish losses until I increased the oxygen lvls somewhat. Now no problem.
Used 2 different test kits. Nitrite will not kick in.
I've even cleaned out another tanks small sponge filter right near intake hoping it would start the bio system.
