You need to get the right filter size or it just wont work. That is clearly why your tank is cloudy. just stick the new filter in and thats all.
I would start with a filter that is rated for that tank size and then expect to add another one when your JD is larger (cichlids are messy).
Which 'instant cycle' product did you use? I've heard that chilled kind (Biospira I think but maybe having a brain fart) actually does what is advertised. As for other products, they are not the 'snakeoil' some people claim, but they also don't do exactly what they say. I used Nutrafin Cycle for a fish-in when I first started up (oh man did the guy at the LFS see me coming). I had to do 30% water changes every day to keep the fish healthy, but to the product's credit (take that part about shaking it first very seriously), I was fully cycled in 18 days. I wouldn't spend the money on it again (I now cycle new tanks with my dozen or so filters - especially the sponges), but it did save me from three more weeks of daily water changes.
Regardless, unless you used the really expensive stuff, you need to get on daily water changes until it is fully cycled and get him a real filter.
I used a big al's multi purpose bio-support It establishes beneficial bacteria to the filter, aquarium surfaces and water and its helps the fish stay healthy
I know many people around here who will put a good 7 - 8 teaspoons of it in a 60 - 100 gallon and it is ready for fish soon after. There is also the way of adding 2 teaspoons every few days but that allows more failure. if you add the full amount straight away you have a better chance for more beneficial bacteria to form and be successful
Anyways, as I said im picking up a filter today so it should be okay
