Gsp help

[Ragunan]

I got this piece of gsp a week ago. Since then the only difference I noticed is that there are a few glowing dots on the mat which I’m assuming are the gsp itself.
So how long does it take to come out?

A lot of things left unsaid ,parameters , flow , placement. I noticed u have it up on some rock work . Not u can’t have it there, just thinking it would probably better if u started with it at the sand level and weekly move it up to where u want it to go a little at a time, also low flow areas are a good place for it. But all of this is secondary to how well u keep your water

assuming your tank is healthy....I had gsp from 2 different sources. 1 opened immediately, the other took some time. Start w it in low light, don’t mess with it. Eventually you’ll b trying to keep it from overgrowth
