I dosed ammonia up to the picture below 0.5-0.75 and 20 hours later the results are 0 and 0. I am planning on doing a massive water change (+/- 90%) and add fish today, only starting with 2 or 3. Angelfish, Rainbow shark, and one my last kid picks out. I have already adjusted the heaters back down to 78.5, am I forgetting anything else before I add them?

When did you start the cycle?

Nice I thought it was something recent, I'd say your pretty much cycled. But what can you do also is try to dose ammonia upto 1ppm see if it goes to 0 after a day. not necessary but gives you more confidence. Also I'm not sure if you have any access to Seachem Stability. I use that everytime I add new fish, again not neccesary but just a safety precaution.

Just wondering why were' you planning to do upto 90% WC? I think 50-60 should be enough.

My Nitrates are very high, and yes I have stability.
Check your water source maybe there's nitrates there to begin with. You might get a minicycle if you change that much water. I use stability every weekly water chagne or when I introduce new fish/es

I think you are fine to do a 90% water change- I disagree that it may cause a mini cycle. I would consider adding one fish at a time to allow your B.B. to adjust. I don’t know how big your tank is, but I think both of those fish need a fair amount of space. Good luck - I am no stocking expert.

I have a 46 gallon tank, so it should be fine.

Changing water won’t cause you to have a mini cycle because beneficial bacteria grow on solid surfaces, they don’t float in water. I agree with Mom2some in adding 1 fish at a time so you don’t shock your beneficial bacteria.
