Hi everyone! Am super new to fishlore, though I have read past threads as a guest and now I'm begging for help.
I have read that amquel/cycle is not a good combo on this site.
I have had major crash and I'm frantic. My
pH is like zero (six or below), my
ammonia is so severely high it is off the chart, my
nitrite is fine.
125 gallon tank with lung fish in it. Put seachem flourite black as substrate and added plants. I added some water, water was low, added a lot of amquel, and then added cycle. A day later a complete crash.
I have always used cycle and amquel liberally.
What do I do now?
Do I do a complete
water change? How much. Do I just let it go and hope it makes it? I did do a 1/2 tank water change as soon as I saw the results, but still no change...
I had never heard that cycle and amquel can be so dangerous. Why do they make and sell these then

?
Help me out, so I can fix this situation. At least it's a lungfish, but still with such bad water it will affect him in time.
There is some wood in there from my other planted tank.
Also, what should I use to condition my water? And do I never add bacteria? I have always replaced bacteria! How about Tropical Science? Really like that too. Ever heard of Geo Liquid? Yes, you could say I'm addicted to chemicals, but have never had a crash before.
Thank you.
