My 40 gal coldwater tank sprang a leak this weekend. Of course the brand new
60 gal tank hasn't been set up yet. We managed to get the fish into our old
tank, using the from the leaking tank and have hopefully sealed the main
tank. It's been drying now for 56 hours so test time is this morning ! My 4
fish - a moor, a celestial and a fan tail (all over 3") and a small
pearlscale are currently in a 25L (yes 25L!!) tank so as you can see I need
to get them out of there ASAP. At the moment I've done nothing with the old
tank other than drain it. Of course it will mean adding totally fresh water
so should I leave it unwashed (been empty since Saturday) to try to preserve
the bacteria etc or should I use this as a chance to wash all the gravel and
rocks etc. What about the filter - I obviously don't want to wash the
sponges but will it be ok to use it unwashed?
Many thanks for any help
