High Ammonia after 2 50% w/c

Oh I agree with that. I think he doesn't want to move the fish out to the 72 if he doesn't have to, sounds like the 72 is still ünder construction. But if he's got very little good bacteria in the filter, it's best to leave alone whatever good bacteria is clinging to things in the tank.
 
Post what the ammonia level is after you do the 50% water change. That alone is going to make the fish feel a whole lot better. And get some established biofilter in your filter. What type of filter do you have?
running test now. I have a rena filstar XP3 and a regent something. Its a copy of the penguin bio wheel 330 with out the bio wheel
 
So you are getting it down by water change dilution. Can your girlfriend do another waterchange for you after she gets home?
 
You say the tank is overstocked. Did you add a bunch of fish recently?

I'd add an extra filter and fill it with filter media from the established tanks.

Do you have live plants in the tank? Lots of plants will also help.

Feed very lightly until the problem resolves itself.
 
Yes she said she would. test number 4 underway.
test is .00ppm. Im going to have her test it every hour and write down the readings.

from the sounds of things I suspect you had a mini cycle..

or something died and is stuck somewhere. the source showed 0 so pink is right..it is definitely something in the tank.

btw,, bored again..never.. I mean never clean everything in an established tank.at least not at once.. even a 100% water change will not reduce the bacteria count by much.
however, cleaning the tank walls, subtrates , ornaments etc..will have a significant impact on them..the bacteria will cling to any and nearly all surfaces in a tank.
while most of the bacteria (or a significant number) reside in the filter..cleaning everythong to make it sparkly clean may send your tank into a mini cycle.

I suspect in this case the change out of the substrate may have had an impact on the bacteria..especially if you had much suspended pariculate in the water column..this could ultimately cover the filter media and could sufffocate the bacteria..sending it into a mini cycle.
with that said.you have other tanks running..transefer some of the bacteria into the tank that is suffering..(squeeze a sponge, or other filter media) into the other tanks filter.
this will jump start the bacteria that is MIA.

monitoring the water is the best way to see if the bacteria have recovered.
