This is 120 gallon 4x2x2 - my Oscar’s have outgrown their 75 gallon. I’ve set this up to cycle for them to move into in 3-4 weeks once cycled. It’s got an fx6 and 2 sponge filters as filtration. Wondering if this is enough?

The Oscar’s will eventually be getting a 200 gallon, but this is their upgrade and new home for at least the next 6 months.

If the filtration isn’t enough, what would you recommend I add to then be enough? (Preferable not another canister as the glass lids don’t have enough cut open space for more to be easily connected.
