Really like the look of gsp covering the sump wall in a Fluval 13.5
If I get a nice chunk of gsp and epoxy it to the wall will it naturally attach to the sump wall as it grows? Or do I have to put epoxy all of the sump wall for it to have something to grab?
Was thinking of it does just grab the wall maybe getting a frag rock holder and just affixing it to the sump wall.
Any tips??
Thanks in advance!
