OK, I figured I would start a new topic to help me with all my questions and needs. First,
I just bought a 75g tank with a glass cover, and now I'm thinking the glass cover was a
mistake and a waist of money. I'm curious if it would be beneficial to maybe return the all
glass cover and maybe invest in a canopy instead of the all glass cover. Also, I've been
told to use a sump/refug instead of a wet/dry or canister, but am lacking the knowledge
of how to setup, and maintain a sump/refug. Id also like equipment suggestions as far
as maybe the sump, lighting, filter system, skimmer, etc., anything necessary to run a
sufficient reef aquarium. My tank is not an overflow tank (the ones with the holes in the
bottom) so would I need more for a sump/refug, or would I still be able to set it up
without the overflow. Any advice, suggestions, or opinions are much appreciated and
well be awarded with me having more knowledge and a better understanding of what I
need to get a fully functioning reef aquarium. :D

Opinions on glass covers are mixed, although most will say get rid of it. It slows down oxygenation and also gets covered in salt, which prevents light penetration. On the good side, it reduces evaporation so you have to do less top offs.. Of course evaporation is needed tool cool the tank.
Refugium/sump's are easy. Either put a tank or rubbermaid container under your main tank. Hook up an overflow box to your main tank that drops water into the refugium, and then have a pump/powerhead that returns water back to your main tank. Make sure the outlet hose for your pump into your main tank is above the water line. If not, during a poweroutage, the display tank will back up into your fuge and overflow it.
I have a screen in my fuge that seperate it into two different areas. The first area is where the water from the overflow gets dropped. In it I have two different types of macroalgae. The algae absorbs alot of harmful things from the water, including nitrates and heavy metals. In the other section I have live rock without predators. This gives the pods a chance to breed without being eaten. The bigger, free-swimming pods then get sucked up the pump into the main tank and act as a constant food source. You can also put stuff like a heater in here to keep it out of main tank.
Keep the marcro algae away from live rock and free floating, it makes it easy to prune it. the stuff grows like crazy and about every two weeks I throw away a handful. (nutrient export). not only does it keep nitrates from building up in your tank, it also keeps algae from growing in your main tank. You will also want to put a deep sand bed (DSB) in the refugium (and in your display tank if you want). This is a breeding ground for good bacteria and pods, and in my opinion, the best looking bottom for a tank. Just get 3-5 inches of sand and put it on the bottom. Without predators, the LR in your fuge will propogate the sand in no time. In my opinion, buying live sand/miracle mud isn't necessary for a fuge.
Skimmer/filter. If you have enough LR (1-2 pounds per gallon) and keep your fish to a reasonable number, you definitely can get away without any kinda filter. Others will swear by their skimmer, but I've never had one and have no problems maintaining good water quality. In my opinion, instead of spending alot of money on a skimmer, spend it on extra live rock for your fuge and display tank.

Without the glass cover, what would I use to keep fish or snails from getting out of the
tank, and would there be a way to maybe prop the glass cover open on the front and
eliminate the plastic strips on the back (which I will probably do anyways to accommodate
piping for the sump/refug if i do go the way of the mighty refugium :P) to allow proper
cooling and oxygenation or aeration of the tank? (Keep in mind I would only be able to
do this for 4-6 hours a day due to the fact I have a frisky cat that likes to pick on things
smaller then it).

Also, I read that with a sump/refug the temperature difference would be about 2* so
wouldn't the cover be beneficial to keep just a little more heat in so the temperature
doesn't drop to low.
