Food for thought....
I have a 60g (same dimensions). I have two Aquaclear 70 filters. The first is a dedicated bio-filter that uses an AC20 impeller for reduced (trickle) flow. It is filled with a packed mixture of Seachem Matrix and Seachem De*Nitrate. This filter is rarely touched and as mentioned, the flow through is just a trickle. The other filter is filled with sponge and floss and sometimes carbon, Nitra-Zorb or Seachem Purigen. It is primarily mechanical and serviced once or twice a week. It is throttled down all the way for minimum flow/maximum re-filtration.
I think two AC110's would be too much flow as combined, they would be up to 1000GPH.
As far as cycling, even with a bio-seed, it can sometimes take 4-6 weeks to cycle a new tank. The process doesn't even begin until there is some ammonia source, even if you add a bio-seed. In some cases, cycling can be 'instant' if enough beneficial bacteria/archea are initially added, but this is somewhat rare and most of the bottled products have organisms in stasis that take awhile to come alive and reproduce.
As far as other/general questions about cichlids, you might go to the cichlid sub-forum: Cichlids
