sam.basye, I wanted to respond to your earlier questions.
I think I've just about worked up the gumption to remove the turtle grasses, but I've got a bunch of "life stuff" coming up, so I won't be able to do it for awhile. Plus I have the berghia nudibranchs coming in about a week and a half, so I'll want to keep everything stable while they do their thing. So yes, it will happen, but no, I don't know when, at this juncture.
The foam wall is still solid. No crumbling, no moving, no discoloration. The only change is the amount of life encrusting it-more! The fake mangrove root also continues, perfectly intact. I have knocked a root lose, while trying to secure sponges, etcetera, but was able to re-mount it with no trouble. I'm especially proud/relieved it has held up, given the vibration put out by the powerhead within. So the fake parts are all good! At this point, I'm really just trying to encourage more life to encrust them.
In my vision of the next dream tank, I'll have another fake wall, but with more variation and overhang. With the extra thickness at the top, I want to incorporate a sloping "beach/shallows" zone to precede the overflow. I also will do new mangrove roots, but more stylishly!
