Yeah that's what I don't like about it, sam.basye.
But, it works for practical reasons, for now. It's an overlapping seam in the pond foam that holds plants perfectly. Unfortunately, it's pretty straight, so they're all lined up, up there. That's an interesting thought, on any future possible fake walls. There are several more, planted on the substrate as well. The GCE portions are big! My hope is that they will grow and spread, and will naturally, get more natural.
So it's a temporary unnaturallity. I'm sure I'll be adjusting them, as I see what I want. Overnight, one in the middle, fell down onto the DSB. It helps to break up the line, so I'll leave it. Nature finds a way.
I guess the same goes for my lovely rubber bands. They're not pretty, but they present practical advantages that can help me achieve my goals. But it does bring up the question, when is it ok to have unnatural additions to your aquarium, and when is it not? For me, it's ok because my tank is bouncing back from hypo. But at what point is it 'done'? For photos?
It's a work in progress. So I don't mind a little less perfection to get there.
