If they were siliconed on top of the glass it would be pushing ALONG the bonded edge not away from it... know what i mean?

Can anybody comment on this i am going to be getting the glass cut soon... Thanks

just finished siliconing my second tank together last night and i put the sides on top and did so with my last tank and it seems to work fine.

-gotta admit for big tanks 60+ your better off buyin' a tank (unless u have some unique idea that hard 2 find) but as for the bigger tanks, making it sounds very logical when u look @ some of the prices...big $$

I've been doing some reading on this. Apparently, since the bottom pane is generally thicker, it makes sense to silicone the side panes NEXT to it instead of on top, so that the area where the two connect is bigger. More area, more silicone, stronger bond.

I don't think I'm explaining it well...does it make sense? I was at Wai's the other day and inspected the big a$$ display tank there, and his were also designed this way.

Chef's right it will be a stronger bond provided you go with a thicker bottom pane if the side panes are siliconed on the outside instead of on top. But i find it easier (and with a 40G it won't make a difference really) to silicone the side panes on top. Myself and Russ built a number of tanks and haven't had any problems.

A couple tips though..

1. Use thicker glass than you would need (if you can).
2. Measure twice or three times before you cut (of course this is a moot point if you are buying the pieces already precut).
3. Lubricate your glass cutter to help it slide/score the glass easier. (WD40 works good for this)
4. Use lots of silicone but try not to play with it too much trying to make it "look better". The more you fiddle the worse it will look. (True Story..:mrgreen:)
5. Always work with a couple cold ones near by.

Good Luck..

P.S. Moving to the DIY Forum.

Well have fun with it and post pictures along the way.

is having the bottom pane thicker really that important if your tank isn't that tall but has a large surface area. say 24X12X24 (L.H.W)

My understanding is that having a thicker bottom pane serves two purposes:

1) For the stronger bond, as I mentioned above
2) If you want to drill it, having thicker glass will obviously be stronger, and help maintain structural integrity

I have very little experience in this practically speaking, though, so perhaps others could chime in!
