Er...it is in inches obviously...lol...common mistake.
I can manage the weight with added wooden panel supporting the tank and sump right up to the bottom floor as extra stand.
You are right. the materials you described of the furniture are not solid wood and if wet it will expand and the lamination will be peeled like a dead skin. Agreed, even if not wet high humidity can cause condensation and the sponge like materials will absorb the humid air and convert to water. There are just too many openings unsealed lamination between joints and all the edges. Gone! my idea and first tank before I could even get started
. But what do you think Pat, if this works if I cover/laminate a layer of plastic wall paper all over the surfaces of the furniture? A kind of wall paper made of plastic/PVC
/vinyl material and it comes with ready adhesive on the adhesion side, something call self-adhesive wallpaper. See pix. Where there are joints I will overlap these areas and make it airtight.
What do you think a tank size 37"x12"x15"(H) and a sump 30"x12"x18(H)" too small? The actual water level will be 11" and 10" high respectively. That is provided I can make use of the space at the furniture.
I have no worry about the tank size for having my "2nd tank". except I cannot decide an ideal location in the house as all furniture are already in place. I am thinking if I can move the table lamp and have it there with the tank length back (5 feet") against the wall. See pix. As you can see it receives indirect outside sun light and maybe good for coral? or algae instead?
What do you mean by a deep sand bed? How deep is deep? 6 inches? I afraid that will take up too much water volume from the sump unless I partition an area and divide the sump somewhere in the middle. How is this deep sand bed help in reducing nitrate? No water if flowing thru it? Sorry too many questions.
