Will GSP grow over algae?

[Thunderrap]

I have some GSP that I'm trying to grow on the back wall of my 15gal Peninsula. It had some decent growth for a bit then seems to have stopped. I'm wondering if it's because some algae is also growing on the back wall.

Interesting, I have wanted to try this and curious to the answer. Wonder if it will grow over coralline to?

Bump, just trying to get some answers. I’m worried about taking a scraper too close to the GSP cause it took me forever to get it to stick to the back in the first place and for it to grow as big as it has so far.

Have you had any luck with this question? I’ve started gsp on the one corner in my tank and there are signs of algae inbetween, wondering if I should clean it off or leave it.

I don't know about GSP but my zoas are completely covering a portion of my back wall now right over the top of the coralline and algae there so I speculate GSP will also. I also have acros encrusting on the back wall covering the algae already there.

In my tank the gsp grew over top of anything in its way. The only things that I have found that prevents it’s growth are aggressive corals that sting it.

I’ve had it grow over coralline before but not green hair algae for some reason maybe it can’t attach.

I don’t know if it’s because of the algae or something else but my GSP has stalled and just isn’t growing.

Coraline it will grow over. Others it will not

My gsp has been growing on my back glass for several years and while I may not have long filamentous algae on the back glass, it has definitely grown over surface algae that wasn’t coralline.
I would guess that large amounts of long algae may stop its growth, but I couldn’t say for an absolute fact either way.

Once mine runs out of space to grow on the glass surface it begins growing on itself and comes out from the glass in finger like projections.

My LFS told me it needs clean glass to continue growing when I asked the same question, my back glass is not clean like my front glass (scraped) but my snails and urchin keep it pretty clean and its still growing. So doesnt need to be 100% clean but the cleaner the better

Gsp will grow over everything. Ev er y thing.
