Adapting Fluval Edge For Razor Back Musk Turtle?

Im sure you've all heard of the EDGE?

A Nice little tank, for fish.
I recently visited a reptile center and saw razer back musk turtles, they were in a small glass tank (which they were selling with the turtles so i presumed they wernt getting any bigger) with two floors, the bottom floor water and the top floor rocks (i think they were rocks).
I would like to work with what i have got as the turtles are £60 and i dont have alot to play with.

I have contructed a sophisticated paint drawing below.

I would like any help and advice i need to complete this project, im all up for dismantaling the tank, also the tank has guppys in it? With a heater

I Know it would need the water dropped and a ledge installed which i dont mind doing and was going to use some glass ill get cut and glue it using the seal stuff you can buy.

BTW im in the UK before you start reccomending stores

THANKS, also im not just going to neglect the forum as soon as i get an answer i think its a great online community and i will put my knowledge as needed.

yeah it is pretty exspensive but a family member is giving one away so i would prefer to use that. I see your not a reptile man but do you think it would work?
Thanks for the reply

I cannot understand the tanks they were selling with them? Ill whip my iphone out when im next there and upload a few pics of them and the turtle
Thanks For The Replies :goldfish:

Really? Thats really bad . . . The Tanks were like £100 / $175 and then they expect you to buy a bigger tank later. I think i have gone off the idea, i would like one but can afford nor have i any space for a 75 gallon tank.

Thanks Everyone who posted
