Hmmm, I lost a Rosy Barb last night but I don't think it was due to water conditions. I could tell he wasn't doing well because he was breathing rapidly and then started hanging around the heater with it's face pointed straight down. I found on the intake tube this morning
All of the other fish are acting normally and I tested all of my levels this afternoon and they are all okay. Nitrates were around 20 but since I'll basically be breaking down the tank tomorrow to remove the UGF I'm holding off on a water change.
In preparation for tomorrow I have completely set up a 10 gallon tank but it's not cycled yet. Right now it's full with the filter is running, I know it's not doing anything but empty tanks are sad.
My plan for tomorrow is to empty half of the water that's in the 10 gallon now and replace it with water from the 20 gallon tank, should I do more or less or none at all?
Next, move my decorations to 10 gallon along with some gravel (in stockings) from the 20 gallon tank. Move the filter from the 20 to the 10 so my bacteria don't expire.
Now the fish need to be moved, what would be the best way to move the fish? Net'em and drop'em in? Will they need to acclimate to the water (everything is the same as the current tank except nitrates ~10ppm lower in the 10 gallon)?
Then rip out the UGF and remaining gravel from the 20 and clean up any funk that's left behind.
Then put in the new (natural looking

) gravel (I know, rinse very well before adding) and refill the tank. When refilling the tank should I use all new water or should I save some tank water to use when refilling?
Okay now the 20 is full so back go the decorations and filter, again how should I introduce the fish back to the 20?
Now the 20 is completely redone and everyone is happy!!! I'm going to leave the stockings of old gravel in the 10 to help seed the tank with bacteria and then continue to cycle the tank fishless style.
Is there anything I'm missing
