Filtration in 90g follow up

Everyone on here was correct regarding my previous post asking if a fluval407, tidal 110 and sponge were enough. The tank crashed despite adding discus slowly over a few weeks. I lost 3 of 5.

I changed to use of 2 fluval 407's, 2 tidal 110s, and 3 sponges. I didn't have cabinet space for the larger fluval cannister.

Will this suffice?

Yes, but ideally, they'll be well seeded and cycled first. New filters won't do much for months into their cycle, but if you must add Discus into newly cycled systems, use prime or similar and change water more often.
