we recently tore down brutises 55 gallon tank (making sure of no left over critters or whatever got him) when it came to the filters wich are hob's right now that have bio holsters... i places those in the 30 gallon tank thinking the bio would be ok in there for a few hrs while we delt with the rest of it and i tested the tank and came back high on ammonia did i do something wrong??? i placed good bio back in there as i have a back up hob on my 125 for such emergencies so i know it has good bio now but shouldnt the first set survived???

When you say you placed the filters in a 30 gallon tank, were the filters running? also how long had the water been in the 30 gallon tank, anything living in it, or was it straight out of the tap?

is the 30 gal tank running when you put things there?
is there any occupant/s?
how long is the process?

the 30 gallon is a fully cycled tank that is home to a betta and a gold fish for my duaghter this tank has been up and running for 4-5 months now

I am a little confused. Did you put the filter on the tank that has the beta and the goldfish? And it stays running for a few hours? Where did you experience ammonia?

ok im getting ammonia in the 55 Gallon tank that brutis had been housed in... while we stripped the 55 gallon tank i placed the bio holsters from the hob's from the 55 gallon tank into the 30 gallon tank wich is well established with a gold fish and betta.. so the bio holsters stayed wet and oxygenated i dont understand why the 55 would try to cycle again.... we only placed the bio holsters in there since the filters also had to be dealt with to make sure of no contamination

i am confused too. have you check the 30 gal tank after removing the stuff?
i am afraid all bb died during medication, thus, those media do not have bb at all.

yep checked the 30 gallon and it's ammonia is at 0 guess i will just let it cycle and do what i need to i am just glad we hadn't put the little oscar in there yet it's just a couple of kissin fish i put in there to feed the bacteria i THOUGHT was there lol

so you put the bio holsters into the other tank...
i think that alot of the remaining bb must have been in the rest of the filter/media.
you probably still have a small colony in what you were trying to save, just alot of it died off in the transfer and in cleaning the filter.
dunno for sure
