Ok, so update. I'm an idiot. For some reason I thought it would be ok to throw away my Bio Filter... I know thats a very stupid thing to do, so im not sure why i did it. But like most of you figured, I put the tank through a mini-cycle. I have barbs dieing left and right, my eels are probably next. The frogs can't hold on much longer either. On the positive side though, my Algae eaters have never been better. Which is also strange considering the levels in my tank. And yes im swapping water, and I added some AmmoLock to it so hopefully that'll save the fish. I'll post again if it improves.
