Jordon,
Keep up on the water changes for now..You could try the Ammolock but I'm not sure that will fix it. There is obviously something causing this and it will be going through and trying to pin down what..To much tinkering will not clear it up just suppress it..I think (my opinion) that you just need to cycle your tank through and after this you should see a reduction of the behavior. Until the tank goes through a good sustainable cycle though keep the ammonia minimal through water changes. BTW have you tested for Nitrites??
