Quarantine WC

[AmazonMars]

I have five young Duplicate Corydoras with a good quality heater and filter in an unseeded and uncycled 6g Plastic tote as a quarantine tank. I did a 20% water change and about to do my second daily 20% water change. Is this the appropriate amount for a wc on a daily basis for an uncycled/seeded quarantine tank?

I decided to go with my lps’ advice and other online advice I’ve read to NOT seed or use tank water, Especially since my display tank only has fish for a little over a month and a half so keeping everything separate as I’m still looking out for health of some of the newer inhabitants

I just want to make sure that I am doing the right amount of water changes or should I be changing more? Thank you

Best bet is to test the water chemistry and judge from there, since you're basically doing a fish-in cycle. If ammonia is over .25, I believe is the recommendation, do what you need to bring it back under that.

After my second water change, I tested it a few hours later and it is at almost .25 so I immediately added more Prime even though I added more than necessary for the last water change in case. So obviously 20% is not enough. So I ask again, what is the recommended percentage water change that you would recommend for 5 x 0.34 inch Corydoras In an uncycled QT 6 gallon tank?

If, after 24 hours, it's at, say, .5, I'd change about 75-80%. That would drop it to below .1 ppm and give you some time before it built back up.

If it's higher than that, I'd do a 75% change then retest to see where it's at. If it's still higher than .25, continue to do 75% water changes and retesting, until you get it under .25. It's all about diluting the ammonia, so sometimes multiple water changes at a time are necessary. Then you'd test and repeat the next day, and so on.

It was at .25 but I decided to do another wc in case it got too high overnight and I lose more fish so I did a 50% wc
One of them suddenly died within minutes so I decided to put the rest in my main display but another one was already on his side as I put him in and died and now have 3 left of those 5. A 6th one died the day before but I got him missing his barbells and all fins completely clamped so I didn’t expect him to live.
What could’ve caused him to Al Di La so cookies from a water change? Did I overdose on Pime?
