Look up Plenum Filters.

This kind of sounds like what you are trying to do.

the sand may not fall through the small holes of the UGF, atleast at the start. give it enough time and the sand will make its way below the plate.

so basically it's kinda like a fluidized bed filter in a wlay. so, if that's the case then whats the harm in leaving the plate in and just use it as a support for the tube and put sand under/around/above it? that is pretty much how a fluidized bed filter works, right? I mean it is just a canister where water is pumped through sand, filtering out the water as it goes through the sand, and then being pumped back into the tank (so to speak) as clean water?

it's not that my heart is set on using the ugf, i'm trying to use as much of the tank kit i got that I can and if needing to modify then so be it. Plus since it is such a small tank then, I really don't have much room to put devices in it. I am currently running tests on how my temp. will be affected with the light I'll be using to see what my need for a heater is. No heater left my water at a steady 69.6 degree F. I've had the lights on for about 6 hrs. now and it raised it to 73 the last time I checked. I will be doing tests to see how warm it gets on and cool off and then to see what kind of fluctuations will be happening later.

I look at this tank a little different. It really isn't an undergravel filter, because you are not using gravel or sand as the method of providing biological filtration. You are actually using live rock, and live rock crumbles, and then using the riser tube and filter plate as a method of water circulation across the live rock.

so, do u think it would be fine with just the crumbles or should I modify it? I mean I can do anything suggested or just go with my original plans and thoughts. One person did note that You should tech.do not need filtration in a saltwater tank, as they pretty much run themselves.

For practical purposes, in an aquarium, filtration is the process by which we slow down the degrading of water quality. Every aquarium needs some sort of "filtration", but marine aquariums utilize filtration in a very different way than freshwater systems.

The use of live rock and sand is in fact, a method of filtration. They both break down waste, resulting in water which is free of ammonia and is low in dissolved organic compounds. In most cases, a protein skimmer is essential towards achieving this goal. In your system, due to its small size, you are able to get away with just live rock as your filtration method, complimented by frequent small water changes.

right, and that was my original plan, just wanted to double check on the sand issue lol. I've got so many thoughts and ideas running through my mind with this set up.

so I was looking at reviews on the heater i was looking at getting. since it only costs about 13-15 dollars i will prolly get it and attach it to the outside of the tank and quite possibly under it since it doesn't sit flat on the table and has a space for the air pump under the tank. I was thinking that as far as keeping a fairly stable temp. I'd turn the heater off as long as the light is on and then turn it on when I turn the light off. I will also see how it goes with both heater and light on just to test my max temps. to know how cautious I will need to be

I personally use timers on my tank to have lights come on and off. This would keep everything on a nice schedule.

well, I bought my water, the lil heater I posted earlier, live rock rubble for 2 gallons ( might actually try to get another gal. worth if i can find some just slightly smaller to cover some open spots on the bottom but most of it is covered), and a hydrometer. I am waiting a few days to make sure everything goes smoothly. I have not gotten a timer yet, they are all in the mid-upper 30s at all the lfs that I've been to lately. I found some online for 28 and 29. I prefer a dig. surge protector strip style. if any suggestions for better prices please let mew know. I don't have any expectations of free loading creatures in the rock rubble, but would be nice to see if there are. I will post a pic later.
