I used to have 3 175 Watt MH w/ 2 40 Watt Actinic Flourescent, now I have 6 96 Watt PC's (4 actinic).
I use an old oceanic trickle filter with no bioballs in it, a top fathom skimmer (probably underpowered, I just have it tapped onto my return), borrowed a chiller from a friend that turns on about once a week for 15 minutes or so, a wavemaker with two powerheads attached, and 2 returns from the sump (one is on an inverted spray bar that is under the rock and on the bottom). I have around an inch of large crushed coral mixed with aragonite and large chunks (probably around 150-200 lbs) of coral rock that I picked up in Hawaii about 10 years ago. I also run one of the returns through a uv sterilizer, but it hasn't had the bulb changed in about 2 years (I'm pretty lazy about that stuff). I use 2 kent dosers (gravity IV drip) for kalk and supplement with coral vite, iodine, strontium/molybdenum. I may retrofit my old MH's and add them on, but that's a project for another day. The overflow is a hang on siphon box.
The tank is about 7 or 8 years old, it's glass (don't remember which brand). Haven't had any problems with it in the past, hope not to have any problems with it in the future (except for making the mistake of scrubbing coralline algae off and other stuff on the glass - it's made tons of scratches, but you can only see them when it's empty or when it's overgrown with algae which will grow in the scratches.
The main problem I have is with the stand. It's a regular pine stand, but it's very difficult to work with because of the bracing/supports. It's not tall enough for my skimmer either, which is why it's underpowered. If I could drill another hole in my sump (which I can't get to unless I take the tank down) I would attach an independent pump to the skimmer, but I can't adjust flow to it with the height of the stand, so it remains on a lower flow stemmed off of my return.
