Hi Violet. Even if your water chemistry checks out, you still need to remove and replace the tank water regularly. The fish and plants are constantly using up the nutrients in the tank water. So, the water is in a constant state of change. As we all know, changes in the water chemistry isn't good for the fish. I have a 55 gallon tank that gets roughly 60 to 70 percent of the water changed weekly. This keeps the nitrogen from the dissolving fish and plant waste out of the water and keeps the nutrients that the fish and plants need for sustained good health in it. If you're not replacing a lot of tank water regularly, whatever is living in it isn't at its healthiest.So I should keep doing frequent water changes even though my parameters check out?

I guess that makes sense, they'll unfortunately still die off because the damage has already been doneMost likely because the damage had unfortunately already been done...a smoker dying of cancer wont magically recover just because they stopped smoking the week before if you get what I'm trying to say? Water changes are just part of the hobby, just like cleaning out the cat's litter tray and picking up the dog's turds![]()
