Thickness of marine set-up

[Ah Boy]

Hi All

I am going to set-up a marine tank (a FOWLR for a start).

Sourcing for a 2nd hand cabinet tank w sump now.....either 3 or 4ft

My questions is:

Most people say that for a marine set-up, the thickness of the glass should be 10mm or more. Is the reason due to the higher pressure caused by the salt water (sorry my sciene cannot make it) or is it due solely to the live rocks weight? What about a 4ft x 1.5ft x 2ft 8mm set-up

I saw a nice tank 3ft x 1.5ft x 1.8ft curve front tank 6mm glass all round and 8mm base....is this a safe set-up? Safety is an issue as I have a baby at home and I do hope that this is a permanent set-up.

Please advise this marine newbie and science idiot....know that I have got lots to read u...

Anyone one???

Currently running 3ft x 1.5 x 2 on a 8mm setup.... 6mm is a no no.
Not too much because of the salt water, but because of the weight of the sand, live rock etc.

Thickness of glass impt.
Placement of live rocks also must take note, esp since you got baby at home.

Thanks for the advice so far....anymore???

What do you meant by the "placement of live rocks is important"??? Is it that if you stack higher, the heavier and bigger the pressure it is...I am thinking for a more flat set-up with a hill/slope covering the overflow chamber at a corner...quite normal set-up...

What about a 4 x 1.5 x 2ft 8mm set-up....is it too thin as well???

i think "placement of live rocks is important" because that should you not place the LR properly, probably some fishes might knock on to it and cause the LR to fall off and hit the glass. Also should you rest most of the LR on the glass wall, this will add on to the pressure exerting on the glass.

for a 4 ft tank, i think a minimum of 10mm will be recommended. although i am guilty of having 3ft tank of only 6mm...

Salt water is very much denser than fresh water.
(Meaning heavier by the same volume)
For 3 footer minimum thickness is 8 mm and 4 footer is 10mm
Anything less is at your own risk

Hi all

Thanks for all the advice...at least I have confirmed my doubts.

Is it safe for a tank with dimension 60cm x 20cm x 30cm (L x W x H) and 4mm in glass thickness to be used for marine keeping?
I believe that we need thicker glass for marine because of the denser saltwater, but with such low height, will it be safe?

IMO, 4mm for marine...its really a risk ...don't try these. You don't wanna see your tank collapse? Cause the weight of the rocks, water etc will make it very heavy. hope this helps! think twice pal!

4ft if u can go for 12mm.
