Hey guys and gals!

I am getting closer to the stage where I will actually be putting my new tank together for my WTFs. I have just finished siliconing the two sides of the tank that will have the GS foam background, but before I do anything with it..I would like some input on the substrate that should be used on the background.

Right now I am looking at a bag of Coco Soft with the bigger chunks and the fine Eco Earth. I was thinking about mixing the two together to give the background a little more texture.

Would this be okay for my WTFs?

Any help would be appreciated. Thanks!
