I'll eventually post more about this in my own photo album thread on the new foot deep breeder tank I'm developing, but I love how this came out so I though I'd share it now
shame my photography skills and camera suck. That's a medium size
X shaped piece of cheap Fellerstone Malaysian Driftwood, a Hydor LED red light, CaribSea's peace river 1-2mm gravel, and the water is coming from my XP3 water outlet piped using 1/2" tubing and a rounded elbow, under and up after it's gone through my vortex reactor. This gravel geyser has been running for days now, and I have not had to resupply the gravel to that corner at all. It makes for a really great visual effect day and especially at night when the lights are out, and is completely harmless to even the smallest of fish who all seem fascinated by this corner.
I could mount the LED buried in the gravel pointing up into the geyser, but I didn't want to waste another $40 just to bring the gravel level of my whole tank up another inch, as this tank will only house shallow root plants, so it does not need more than the two inches already there, only to end up stealing another inch of swimming space from my fish.
the lesson here; do your own thing - don't just copy everyone else's tank
sadly, my pictures barely do this thing justice;
