I have decided to take all my fish out of my 90 gal FOLR tank and put them in a QT for 6 weeks. Do i have to continue to run my heater in the Display tank with no fish?
 
I would, just to keep whatever biological filter that is established happy. Any particular reason they are going into QT?

You can also raise the heat in the tank to speed up the life (and death) cycle of any suspected parasites in the tank that require the fish to survive.
 
^ all of that.

And I'd watch out when you go to put the fish back in the main tank - depending on the current bioload fully stocked, there will be die-off during the fallow period, and I'd add the fish back slowly. I'd also purchase a Seachem Ammonia alert to put into the tank when you start putting fish back in so you'll know if ammonia builds up.
 
yes u do have to maintain the water parameters. if u dont keep salinity between 1.009-1.026 and temp between 74-84F while keeping ammonia nitrites 0 and nitrates under 20ppm, also need water movement or skimmer u will lose the beneficial bacteria keeping ur tank alive and filtered.
This might be ok if u dont care and will clean the tank out and re-start the cycle and start from scratch but if u dont wanna go through all the hassle of cleaning and cycling again then keep tank/equipment running just as u normal tank along with feeding it every 3rd day. remember no food no ammonia no bacteria no cycle.
 
fallow tank

I have a 90 gal fallow tank for 2 weeks now with the same levels of ammonia and nitrate as i had with fish in there. .25ppm and 20ppm
confused
 
Do you use treated tapwater? If you're treating tapwater, many ammonia test kits register TOTAL ammonia, which includes the bound, harmless ammonia as well as the toxic "free" ammonia. This may be what you're seeing.

Your nitrates really shouldn't change TOO much unless you're ghost-feeding the tank (as you should). Then, I'd expect them to rise a bit.

Are you ghost feeding the tank? You need to feed the bacteria you have established or they will die back to whatever level of food is available to them.

There's another thing that can happen if you ghost feed a tank TOO much...you can actually stall the nitrogen cycle, however, I assume this isn't the issue.

HTH
 
ich parastie i couldnt get rid of so i decided to let the tank go tru a 6 -8 week fallow period to kill it.
 
I let my tank go fallow for 8 weeks and introduced a QT'd Blue Hippo tang and 2 days after it was in the tank it developed a mild ich outbreak. Now I just deal with it...
 
125 gallons...

Well I've been just waiting it out... it comes and goes. Everyone eats and looks normal... besides a few spots. Feed alot! Try to keep stress to a minimum...

I also installed a UV sterilizer and never had an outbreak as bad as the first one before I had the UV.
 
i read mixed reviews on the UV... i raised the temp in the main tank to 82 its suppose to quicken the cycle of the ich so it can die faster.. 2 more weeks and we 'll see what happens
 
The UV did not get rid of the ich... but this last outbreak was extremely small compared to previous
