Outdoor pond with window - Looking for advice.

  • We are currently upgrading MFK. thanks! -neo
Hi David,

I used an aquarium calculator to calculate the glass thickness, so the piece of glass going in will be 290cm x 60cm.

The glass will have water 15cm from the top so the area underwater will be 290cm x 60cm. For this it seems that 12mm is enough to do the job.

I saw that toughened strengthens the glass by 5 times which is why I thought it would be safer however having read more on that front now the thought that if damaged the window could shatter into thousands of pieces I am definitely agreeing with you and staying away from that!

However with the laminated option it does mean that if the glass broke/cracked for some reason it would hold in place and then you would have a slow leak maybe instead of the water just gushing out in one fall. When I have visions of dead fish all over the lawn this feels like a safer option to me?

I have contacted the glass manufacturors regarding the safety and load difference between a normal glass sheet and laminted to see what they say. I would pay the extra if it was safer. I am surprised there is not more information about this kind of thing online or maybe I am not using good search terms on google! lol

I appreciate anybody's input and advice into this - past and future. Thank you all! :)

How many decades old was it and how big and what region was it in? She's in the UK not much sun there. It should be fine. If you check out the thread I linked earlier he lives in the UK and used acrylic for his window and it's still ruining nearly 3 years later.

It was less than a few years old from somewhere in China. There's video's on youtube of it breaking and splashing all over a crowd of people.

Does the calculator factor in the use of standard aquarium bracing, or is there an option for "rimless" tanks? AFAIK most of the calculators are based on standard aquarium bracing, which for a 2900mm length would be 2-3 front-to-back strips plus a 'euro brace' running along the top edge of the glass. If you aren't going to have any sort of bracing along the top of the glass it will change things considerably.
