Need Advice On What To Do Next

[chrisrm]

i have reposted in this section as i need some help... quick!

this is the old post...

i had some one look after my tanks over christmas as i was away for 9 days they were going to go round evey 3 days to feed them. i just got a phone call to say they went round on tuesday and everything was fine but went round today and eveything is dead because the electric had run out(which i had given the money to top up)im not angry or upset just gutted. they offered me some money but i told them its not as easy as just going out and buying some more fish!

so 3 days without electric obviously cooled the water which killed the fish, but what about the filters? the electric has been turned on now by them but they wont fish out the dead ones and im not back till sun/ mon

will i have to re cycle my tanks or should the bactiria have survived

and this is what i came home to...

took some of the dead fish out of the 350ltank and tested the water using an api kit

ammonia 2-4ppm
nitrite0.25ppm
nitrate 80 prob higher

65l tank dead fish still in there
ammonia 0ppm
nitrite oppm
nitrate 20-40

what should i do now?
there are obviously no fish in either tank i just want to try and save the filters from having to be cycled again.
the small tank seems to be ok and te bactiria must still be alive? but i wonder are the readings from the big tank so high because of the volume of dead fish that were in there?

one more thing, four apple snails i have in there are still alive and all over the dead fish feasting!what should i do with them?

If you do decide to keep the bacteria alive I would do some water changes. Keep the bacteria alive with adding flake food once aday.
Also higher temps multiplys bacteria.
I would also add some myxazin just incase of bad bacteria due to the rotting fish.

Also with the heater not being on due to the electric being off you could of lost quite abit of your benefical bacteria.

Poor things.
