Hydor Koralia Nano 240 vs 425

[Shep]

hey,

So from my old tank I have one of each and I am wondering which would be better for a mixed 20 gallon tall reef tank, for the 240 the total times the tank would be cycled an hour is 18 and with the 425 it would be 27.


Thanks

I would try and get as much flow as your inhabitants can tolerate w/out causing a sand storm. So tinker with it and see how the 425 works out for you.
