Hey guys, so i have a 5 gallon tank, which is still being cycled (3 days in), with 2 danios!! Although, i realized that 5 gallons was too small for any fish really, so im returning thr dans and switching to 10 gallons right away when i go to retun them (tommrow)! So, i was wondering will i have to go thru shole cyxle again?? Also, will i have to wait 2 days before adding new platys again? Or could i just put them in it since i am gonna add all the water from ky 5g to the new tank, and than fill remaining 5g with new water??? Also, im gonna use all the gravel and other stuff to keep my bacterias, but im not sure bout thr filter cartridge, the new filter i will be getting for 10g has much bigger and diff cartridges, so do i jist wash my current cartridges in the new tanks water to add the bacteria?? Please help me before i get my new tank! Thank you so much!!!!!
