Where to put Cascade 1000?

[fishie111]

I purchased a used tank that included a barely used Cascade 1000. I have 4-5 tanks where I could possible use it and I am looking for recommendations on the best place for it. (I am considering getting rid of all my HOBs in favor of canisters.)

Here are my choices:

75G SA cichlid - currently has a Rena XP3 running, the Cascade would be a 2nd filter
46G SA cichlid - was planning to use an XP2, but it is not set up yet (currently running a Whisper 60)
36G goldfish - this is the tank the Cascade 1000 came with, not sure if it is sufficient (currently running 2 Penguin 150s- which is less filtration than I ultimately want)
28G SA dwarf cichlid
20G small community

Thanks!

i have a cascade 1000 canister and i love it great filter i would use it on the 36G tank along with 1 of the penguin 150's. i use mine on a 75G along with a HOT magnum and the water is crystal clear.

36g goldfish, that tank needs all the filtration it can get.
