I am getting ready to switch my 70g to a 90g. My 70g is 2yrs old.
My new 90 will sit in the exact place of the exsisting 70g. So I have to first move the 70g and then put the 90g in it's place. I am thinking of using a spear 60g for the switch, my thought is to siphon water from the 70g to the 60g. As water deplete's from the 70g I will place the rock inside the 60g.
I will also be using the exsisting sand bed.
Q) :?: Should I replace some of the sand bed and if so how much?
Q) :?: Will this switch cause another cycle in the new 90g?
Any help from those who have already done a tank switch, with out a crash, will help a great deal.
