    Hi All

    Could I build a sump with Perspex. It is 17 times stonger than glass. More flexability with regard to drill holes. in general easyer to work with than glass.

    Ye, you should be able to use it.

    I can't see it being any worse than acrylic and loads of people use acrylic so perspex couldn't hurt either.

    The problem with perspex is that it is too flexible if thin. Glass is firmer thus more suitable

    Ps the warmer perspex is the more flexible it is too. With thickness that is not too flexible the weight issue features negatively

    Meh, the same thing... we learn something new every day...

    I've gone to Maizeys and asked for perspex for a tank and they ask me if I want acrylic instead. Hmm.

    Isn't perspex more expensive than glass, anyway?

    Suppose with perspex it would be easier to clean the sump. I have also seen a few sumps that have been cracked or chipped - wouldn't be as easy to do that with a perspex sump (assuming you using decent "thickish" stuff)

    The glue is called Tensol, I used it to build a catch box a while back. I got it from Halls Mica Hardware. Im sure you can pick it up at a signage company as well. As far as I am aware you cannot use silicone for perspex on glass. Over time it does not adhere as well. You can also use Chloroform but not too sure on how well it seals.
