It depends on how much live stock you have left in the 55 that you want to transfer. You have aprox ˝# LR
for the tank. That's not really enough (IMO
) for bioligcal filtration in a tank. The recommendation is 1 - 2 pounds of LR
per gallon of volume (depends on the porousity of the LR
So the bottom line IMO
is that the LR
you have now was fully cured and sufficient for the bioload you now have, but is not sufficient for the increased bioload from your 55 gallon livestock if added all at once.
The rules for adding fish (one per month) don't necessarily change. If however, you double the amount of fully cured LR
and you have a low bioload in the 55, you should be ok.
That would be my conservative opinion.
