I have a 50 gallon tank I'm setting up as a display tank for Malawi. I want to make it run very quietly and be VERY clear as it will be a focal point of the living room. I'd also like to keep as much clutter out of the tank as possible or to hide it where I can. To that end, I'm thinking a sump system would be best rather than the HoB filters which I've been using for years. I'm sick of the messy eye sore they become over time and they are never as quiet as you'd like.
To get water to the sump, I was planning on the 600 GPH overflow like this one:

And the 634 GPH version of this pump (with the head height, it will be a little bit less than the 600 GPH overflow) to get water back into the tank:

To keep the tank water circulating, the output from the pump would go to under gravel jets, ala:

It seems that this:

could be modified so the first layer after the drip tray was a large matt of filter floss. Then everything drops down into the bioballs. That provides two of the three types of filtration.
For that extra sparkly clean, I was thinking something like the 25w UV system run in-line here:

Probably wired in on the pump intake so it will have the most effect (already filtered mechanically.)
So with all that said, am I nuts or is this a reasonable idea? After rocks/substrate, the tank will be no less than 40 gallons. With plumbing and head pressure, the pump will do around 550-580 GPH tops. That makes for about 14-15x turn over (not counting the volume in the sump which will be around 20-30 gallons). Is that too much current for the poor fish even with a lot of jets to break it up a bit? The tank will be relatively open, so the current won't be focused in small areas.
Is the filtration idea going to work at all without it being forced through via pressure? If not, how is mechanical filtration handled in sumps typically? It seems that the drip tray idea works fine as long as there is enough surface area to let the water find it's course naturally over a large area of floss.
Also, the whole "drip tray" sounds noisy, in practice, are these quiet? If not, how can I achieve my filtering goals realistically? One thing I like about this current design is that the ONLY moving part is the pump and that can be isolated for noise quite easily. There are also pumps available that are almost totally silent.
Thanks in advance for the help!
