I've got a 55gal tank with a canister filter and I did a water change last night, And now my WHOLE tank has passed away. I did notice tonight there is a white film on top of the water and ideas? My AMMONIA level is 0, My NITRITE level is 0, and my NITRATE level is 5.0

White film doesnt' sound good.
Did you remember to use dechlor when you added the new water? I'm really surprised that the whole tank died overnight....did anything else get into the tank by any chance (ie have you had friends over?).

NO I have not, however I have sand for substrate so im wondering if i didnt get it stired up enought in the past week and when I did it tuesday maybe it let off some bad gases???

Bad gases kept in sand will, when churned up, produce bubbles that you can subsequently smell of rotton eggs. However, these gases can be dispersed quite quickly in a matter of seconds to a few minutes. The other thing is that anaerobic pockets IME stain the substrate a blackish-purplish color that is quite obvious.
All I've got to say is that while I've had anaerobic pockets form, I've NEVER had fish die from them, and I've never seen a white film form.

Yea I don't know what happened! This is the first time it has happend to me. Maybe I need to just do a big water change and see if that help! Maybe something got into the water that I was not aware of? I di put some algeflex in with my PRIME and STABILITY. maybe it had a reaction???

If every thing in the tank is dead doing another water could cause more problems unless you can find out what the problem was.
Here are a few possibilities.
Dirty/contaminated water supply (what do you use Town or ????
Any type of chemical spray used in the area.
How did you do the water change? Was any of that contaminated?
Did you have the canister turned off or did you clean or change any thing in the filter.
Did you feed them after the water change if so what and when?
I di put some algeflex in
What is this and why are you usung it all?
I know this sounds like a lot of questions but its going to be a matter of elimination

I use the same city water i've always used. And have a python so I dont carry buckets. Yes canister was turn off like I always do. I did change a micro- filtration pad. I feed them before the water change. algefix by api. helps keep alge down

You might want to describe in some better detail what
this white film looks like.
It could be the aftermath (bacterial) of the massive die
off of the fish. Or, it could be particles of dust from
the sand that have attached themselves to an oily film
on the water's surface which was caused by using fish
food with plenty of protein or fish oil.
In either case, after a die off of such proportions, now
would be a good time to tear the tank down and clean
everything. Clean the insides, the gravel, the filters,
the heater, virtually everything that was/is in the tank.
Then, restart (recycle) the tank in preparation for the
