I lost 4 fish a couple of days ago (not my fault) and I lost a fish today. The 4 fish caused nitrites to skyrocket! The pet store worker told me to do a 25 percent water change. I did that. With my fish that i just lost should I do a 10 percent water change. My tank is new so bacteria build up is kind if low so should I

Do you have a test kit for ammonia and nitrite? You should do much more than a 10% change. Most would recommend a 50% change.

greetings.

how much water you sould change when a fish has died depends on how long it has been dead, it's size and the size of your aquarium. but 4 dead fish is alot of bad stuff being released into the water, in that case you sould do much more than 25% initial, and more than 10% daily.
