lol... internally you're spanning a little under 23" and with acrylic thicker wouldn't hurt... plus it's only $15 bucks more.

Hmm I need a good measurement... what should the length so I can tell them to cut the pieces? I need the exact size. The tank is 24 inch wide but inside from glass to glass is shown exactly in the pic I just don't know what to give them... 23 and 1/4?

 

[DarkTang]

Oops forgot pic

 

[143MPCo]

all depends on the thickness of the glass, if it's 1/2" thick and externally it measures at 24", your at 23" internal... sorry about the 11" was trying to fig something else out.

Lol sorry glass is 3/8

 

[143MPCo]

Lol sorry glass is 3/8

23 and 1/4 is it...

 

[DarkTang]

Check pic to see if I'm right, if glass is 3/8 then it must be 23 1/4?

Yes you're right... I know we have not talked about silicone but recommend Momentive RTV108, the manufacture states it's "adhesive sealants" and I have had great luck with it in the past.

Ok sweet I'm telling them to make a sample 23 1/4 by 1 inch to test out first... that silicone is obviously reef safe? Where can I get it?

 

[143MPCo]

give it a week or two to cure, yeah reef safe... Amazon... lol

 

[DarkTang]

Uh oh 23 1/4 no bueno... should I try 23 1/8?

 

[heathd.hd]

If you have a lfs they usually all have aqeuon silicone. Kinda expensive but it's for sure reef safe and a 24 cure time.

 

[DarkTang]

What I have Dap aquarium safe 100% silicone would that work?

 

[heathd.hd]

If it says aquarium safe than yup. Just make sure it doesn't have any mold protection in it.

 

[DarkTang]

Ok cool, how about the strength of the adhesive? Each chamber will have about 45 gallon of water pushing on the baffle, I want it nice and tight and no bowing

 

[heathd.hd]

Lol might wanna think about your thickness of acrylic. Idk.

 

[DarkTang]

It's 1/4 inch, is that good enough?

 

[heathd.hd]

I know people say silicone does not hold that great on acrylic also.
