Ok,
I just bought a FX5 and it has been installed now for a week.
I just scored a 125 gallon tank, to replace the 55 gallon tank.
How is the best way to go about this, since the filter is brand new, should I wait 4-6 weeks for it to cycle before I install the new tank, or since it is so new just install the new tank and basically start the cycle all over.
Please forgive my ignorance, never owned a canister filter until now, and never had a tank bigger than 20 until the 55 came along,
Should I put some of the old water into the new tank? Or just fill it all with brand new water?
Oh and as luck would have it, the 125 gallon also came with a Rena XP4 Canister Filter. Should I run the FX5 and the Rena?
I have two turtles sharing a tank.
If not if someone needs a Rena cheap let me know.
