Ok guys I have a question .
I am getting an existing 90 gal
tank setup ( fish , rocks soft corals etc for FREE
)and I currently have a 46 gal
with some fish, rocks and coral frags.
so basically I have two tanks to combine into one, the 90. how should I deal with the water? do i keep some water from both tanks, combine that and add new SW
water? or take the water from just ONE tank and combine that with new SW
my other option is to put all the fish and coral frags into a 29 gal
setup I have thats already up and running and fill the 90 with new water new sand and all my cured rocks. let it run to see if a cycle happens then put all the fish and frags in the 90 after a drip acclimation?
need some advice..
