Building the landscape

I almost know what the end results might look like. I know I need a false bottom to get more water in the tank which means the water chemistry will be more stable. I have searched the net and been asking around to find out what brand of pu-foam to use for the landscape. No safe results. So at the end I decided to go with a Pattex Universal Pu-Foam. 89 SEK from Clas Ohlson.

Now I have started building the landscpe. Not as easy as I thought.Still got a feeling that it might work fine.
