acrylic glue?

[firehazard]

I'v been doin some research on the web as well as MR about acrylic glue and alot of what i'm seeing used in fish tanks are Weld-on products. now i dont have a problem buying the product and fabricating my project myself but time is money. and was wondering if i had a glass shop cut and put together the acrylic peices they might not be using weld on.

question being... if acrylic glue "melts the 2 peices to bond then evaporates and in time cures" then shouldnt any acrylic glue be fish tank safe?

Just to be clear - what are you looking to glue..a sump? a tank? frags?

We use CA Gel glue to glue frags.
Weldon products aren't used 'in' a fish tank full of water to glue anything but are commonly used to glue acrylic panels as they do 'melt' the plastic together.
For tanks made of glass, silicone is used to hold them together.

im trying to make a filter sock holder out of acrylic that sits in water in the sump. no glass.

Yes, you can do that and definitely use the Weldon glue as they hold the best. Just make sure it is dry before you put it in there and everything will be fine

but back to my main question... what if a weld on product isnt used ( a different brand of acrylic glue) would it still be fish safe?

I can only speak for Weldon.
What type of glue are you planning to use?

As long as they are similar to weld-on they are fine. I am using Craftics #33 with success. You can get it in Chinatown at either of the two plastic stores there. It is cheap too.

I would go with a proven brand.. I used the weld on they had in stock at canal plastic. You need a clamps to hold everything together too. Good luck1
