Hi Alan. The bottom of my tank is NOT a floating bottom - where the ends/front/back are glued to the sides of the bottom and extend past the bottom 1/8" to 1/4". The ends/front/back are glued to the sides of the bottom, but they are flush with the "bottom of the bottom". The bottom, therefore, is one flat surface (other than the 1/32" thickness of the frame). The foam prevents hard surface irregularities (metal, wood, etc.) from forming pressure points against the glass. It also tends to compensate, to some extent, for out-of-level situations.
Thank you. The gap is 1 1/4". Yes. I'll be using some stiff plastic mesh (like Gutter Guard) on the box side of the overflow.<a href=showthread.php?s=&postid=13675753#post13675753 target=_blank>Originally posted</a> by zmckenzie
I love the overflow the way you have it. How high is the gap from the overflow to frame? Will you need to have some sort of guard to keep the curious fish out?

I've never seen clear primer. Where did you get it?

I don't want to appear pedantic but I am not sure what a "floating bottom" is but I was always under the impression (from replies here on RC) that you only installed foam under a tank with a flat bottom (no frame - either glass or acrylic). Normally with a framed tank, the frame is what supports the tank and not the bottom glass and we are advised to support the tank via the frame, but in your case the the foam complies with the difference between the bottom glass and the frame and adjusts for slightly out-of-level stand. Obviously this works so who am I to challenge this method.
Thanks
Very thin (almost invisible) beads of silicone. The acrylic is so tight to the glass that water does not flow between the two. They really did a bang up job on my tank.<a href=showthread.php?s=&postid=13676787#post13676787 target=_blank>Originally posted</a> by 2_zoa
Do you know how they attached the acrylic sheet to the back wall? You can't or at least I can't even tell that piece is in there, and looking at the back there is no indication of any glue to adhere the two panels.
Not really necessary. Bean mentions, early on in his thread, that a valve is really only needed on the siphon pipe. The open channel pipe and backup pipe don't need regulating.<a href=showthread.php?s=&postid=13677847#post13677847 target=_blank>Originally posted</a> by xfifi
why do not you put 3 ball valves as the BeanAnimal's system on the 3 standpipes ?

I thought I would try to clear this question up to the best of my knowledge. There are three ways to set up a glass tank.
The first and most common way is to suspend the bottom. This is done by bring the glass on all 4 sides a 1/8 inch down past the bottom pane. Thus a floating bottom as glassreef describes it.
The second way is to have the bottom pane of glass rest on the surface with the 4 sides resting on top of the bottom pane. All weight is on the bottom pane of glass. A foam bottom is needed to keep the bottom pane of glass from fracturing.
The other way, which from what I understand is how glassreef has it is the bottom pane of glass rests on the surface just like the other one. However, instead of the 4 side panes resting on top of the bottom pane of glass they surround the bottom pane of glass and are flush with the bottom pane of glass. So all 5 panes of glass are touching the surface. The foam keeps the keep the weight distributed.
I hope this helps a little.
