I just had a brain-flash (doesn't happen very often, I know
). when I ordered Zen's tube, I also ordered a tower for Zen. I put the tower in today along with his water change.
Here is the thing: I ordered several plants that I think will look lovely in his aquarium and make fun hiding spaces and help tank conditioning. Question :shock: how to tie down those plants so they stay below gravel substrate. Well. It seems that some people use this SAME plastic mesh (for hold-downs) that the tube and tower are made of. OK.
So then, I think, we have his new tower which has a square mesh base for under-gravel hold-down.
Ahah! I have a Cunning Plan: Take the bare-stemmed plants I will get, and thread through base of Zen's tower. Just a few, I am thinking the one plant, four stems, probably the Dark Red Ludwigia. These plants will be on the outside, not the inside.
There you go, just a thought, and I will post pics if, and only if, it works (which it should!).
Sometimes I surprise myself.
