Thanks for the help.
hey scott , yeah its denny here


basically remove any of the white shims between the tank and styrofoam and start to fill with water as it gets heavy it will settle provided your stand is plum and square and level.


also your silicone is on its way my buddy

ps....looking good man looking good this is gonna be a sweet build


cheers

OK - I kinda thought I saw silicone there

Yes, shimming between the tank ply and styro won't do anything
If Denny is comfortable with you filling it as is, go for it

I can see where shimming only the outside edges may pose a problem as there's no 'trim' that the glass is sitting on

Hey Denny,

The stand is square & plumb according to my 4 ft level and all the measurements. So I don't know where the little droop is coming from but if you're not concerned I will start filling it sometime this week and see how it settles.

Could you also send me a small piece of 1/2" glass the same size as the side of the external overflow? I need to replace the one I broke out.

Thanks again!

with large tanks we build right on to the plywood, because of the strength of the silicone we use once cured removing it would be alot of work and would more than likely end up with chipping/shelling the glass.

the plywood base is used to ship safely and so the tank can be slid around untill its filled with no damage to the bottom.

for smaller tanks we build on a foam base.

Nice looking build! I've always loved this 2-panes viewable style.

So what will the thicker foam (1") accomplish? Will it provide more compression than the 1/2"? Plus, I have calculated the space between the header and the tank pretty tight to fit in the return plumbing. If I take away a half inch things may get dicey.

I could switch if it's better for the tank in the long run.

when you put water in there and Glass having no flex to a point. the Styrofoam will give that more support. so on heavier tanks thicker foam is used

I have no issues with the 1/2" styrofoam. Ask Dave or Denny which thickness they suggest.
