Ok i know everyone has already tried the cocopeat silicone background...
problem i noticed is that the cocopeat layer will drop off pretty quick actually.
Also the silicone will at certain areas, shrink and if u are using white PU foam below...it will show...looks pretty ugly
like if your "black pants being torn and revealin your white underwear" kinda look...awful

Any other possible ideas that may help ?

I've checked flevopol but have no idea what it is or how to use it...im lookin into other longer lasting and stronger gripping glue solutions as i have one extra tall exoterra tank bein fitted up
wanna make it my greatest tank
