great group shot christian.. looking good.

PLEASE HELP' ANYONE ONE LINE? WOKE UP 2 FIND 2 FISH DEAD AND A NOTHER IN SHOCK. 12 HAD NO ELECTRICITY 24 HOURS''
NO AIR ONLY ONE FILTER WORKED.
I CHANGED SOME WATER,anything else i can do? QUICK!!!!!!!!!!!!

if low oxygen is the only problem you can use 1 teaspoon of 3% hydrogen peroxide per 50 gallons every 6 hours to solve the low oxygen level. be very carefuly to measure properly and you can also move the water manually with a bucket just create flow and agitating the surface will increase oxygen.

thanks, what could be other reasons 4 shock? nitrate level? ph?

you have electricity now ??? airstones stright in will help . i had aprob with canister failure and lost fish.. but i had heat..

possibly tempature change, low oxygen and decreasing ph due to the low oxygen. probably a combination of those.

all working now, so i just have to wait and see?

good luck man, hope you don't lose any more.

invset in some battery powered airpumps i am ..lol never be too safe..

If it was oxygen related, they should start looking better after a little while. Hope you don't lose anymore. Good luck.

Now i understand what happend.
It wasnt a power failure but one of the cables came loose, there was no air pump and the smaller one of my 2 canister filters stoped as well.
My large canister is big enough to work on its own so it could only be lack of oxygen.
Could water with no air pump kill my 2-3 healthy fish within 15 houres??? so quick??? so deadly????????

i don't think so how packed is your tank my big tank only have one pump in it and it does fine heavly stocked as well its probs something else
