To tag along to Mr Ono's question about power heads, I saw yesterday in Seattle a 100g display tank where they used strategically placed 2" acrylic posts to lift the entire large pile of live rock off the substrate. This created an interesting look, as critters and spectators alike had free access to a bunch of previously unaccessable nooks and crannies.....but more importantly it increased circulation greatly. He had a flute-like inflow tube nestled in the substrate down under there. The pro's of this are obvious even to me, but he said the downside is that many critters (ie starfish, crabs) cannot climb up from the substrate onto the pile (he did have two places where the rocks reached the sand for this exact purpose). Anyway, I was wondering what you all thought of this interesting way to increase circulation and decrease detrius buildup, etc...?
Are there other alternatives similar to this that also increase circulation?
I think I liked it, but will reserve my opinion until I hear from the "esteemed panel". :-)
Gratefully, Mike
