Has been awhile since I posted, but I have continued to lurk from time to time. Hope everyone is doing well!
Things are going good on my end, in fact, my wife and I just bought our dream home. And as I begin to contemplate moving, my fish tank of course comes to mind.
The reason for this post is that my current setup is about 6 years old, and I figure this move is as good an opportunity to "upgrade" components and equipment as I will ever get. So, I am looking for some advice and input. I haven't really kept up with the industry or new technologies, but I am sure some of you have, so I am hoping you can take a look at what I have and see if anything stands out to you. If something screams 'upgrade me!' I want to hear all about it.

Setup:
75 gal tank
4 clown loaches (I lost my 5th a few years back)
2 plecos
5 or 6 dither fish (tetras)
2 AC 110 HOBs
1 Filstar canister (purely used for bio, because I HATED taking it apart to clean it)
Coralife Aqualite (that looks like this: http://globalaquaria.com/images/products/RES53014-2.jpg)
Some generic heater
Sand substrate, driftwood, and some very low maintenance plants (anubias) that look like hell
As you can see, I am kind of over filtered and under stocked (at least I think)... but this was because after a nasty ich outbreak a few years ago, I've been too chicken to add more fish. So as dither and other non-loaches have died off over the years, I haven't replaced them.
Also, I used to have a river tank manifold in there, but pulled it a few years back because I could never get the flow right and the water always seemed dirtier than I prefer... it seemed like the currents were suspending larger particles in the water and the filters were not grabbing them. Anyway, I might consider adding it back in during this move. I'm not thrilled with the flow pattern that those AC 110s create... the back of tank to front of tank sort of thing.
So, I browsed a reputable aquarium store last week and it felt to me like, in particular, aquarium light technology has changed. The new LEDs look nice. Any thoughts or advice on them? Also, it seemed like there were some new canister filters on market. Anything I should be looking at?
Ohhh, I could go on and on... but I hope I have enough info here to start a conversation.
Thanks!
