GHA in Sump

[James Oh]

So I have GHA growing on my marine pure block in the sump but not the DT. Is this common? I mean I know I should be grateful that it isn't in the DT haha but it seems weird that it would grow in the sump and not the DT as well. Also should I remove the GHA from the marine pure? I'm worried that if I mess with it it'll end up in the DT =\.

Are you lighting the sump?

 

[rygh]

You likely have GHA in DT as well, but it is being eaten by herbivores and snails.

You can remove it, but be careful since marinepure blocks are pretty fragile.

Yah sump is being lit by this amazon grow light.

I'll try to be careful not to crumble the marine pure. I do have 4 snails in DT but didnt think only 4 was gonna be enough to cull the gha.

How long is the GHA?
