Any help is great, thanks in advance!
There is little benefit to saving the water from the three tanks.
A better option would be to set up the 55 gallon the way you want it,fill it with dechlorinated water,let the tank run for a few days to ensure that the heater and filter work correctly ,and then move one of the filters from the ten gallon tanks to the 55 gal and let it run along with the new filter for the 55 gal.(three or four weeks)
You could in this way SLOWLY add three or four small fish each week until the fishes have all been moved.
Could also scoop up a cup full of gravel from one of the other tanks and place this gravel in mesh bag or toe section of ladies nylon(clean
) and place this in the 55 gallon tank and leave it for a couple weeks.
The good bacteria you need for a new tank will largely be found in the filter from one of your ten gallon tanks and in the gravel from same. By moving one of the filter's and the gravel from one of your existing tanks assuming they have been running with fish for a couple month's,,you will be transferring the good bacteria from one tank to the new tank.
this does not mean you can immediately stock the 55 gal to capacity but it will help seed the new tank with the needed good bacteria and cycling time is greatly reduced.
Were it me,, I would keep one of the ten gal tank's in operation and use it for quarantine tank for new fishes before placing them in the 55 gal.
