Zero Edge

what a ridiculously impractical idea.
I'm sure it looks great in a store,
but it must be a leveling, water top
off nightmare to actually own, and
who stands over their aquarium to
admire it at home? if you have a
wood joist floor, just walking by
this thing will only disturb it :hihi:

if you neglect to top off the water,
can you imagine what a smelly mess
that outer edge gutter will become?
whenever the salt water dries on
the outside glass, it must leave some
awful mineral stains behind each time.

with that water spill over, it must lose
an inch of water a day in the winter.
I lose a 1/2" per day without any
water movement in my 18x30" tank,
which has a similar open top surface.

Let's try not to salivate over every
new $$$ gimmick that comes along.
it only discourages people from this
hobby in the long run, by cheating
them out of money that could be
better spent on useful equipment.

That's the main problem with these things. I can just imagine some of the folks that drop money on stuff like this.

I love the idea and the visual, we build the same concept into swimming pool and hot tub spill-overs and negative edges. I've never setup a sump so wasn't sure about how evaporation would work out, but I would definitely have an autofill whether it came with or had to be added by myself. Topping off open reef tanks is a constant little chore anyway, regardless of what tank you have. If I was going to drop funds like that I would go all out.

I don't entirely agree fish won't stay in it, there are plenty of reef species that know to stay in the water unless they want to become bird food. I've had a goby in an open 8gl for over a year.

I don't think I would plant it if I had one, definitely hard corals and tridacnas with an MH combo pendant. Plants are cool to look at from the top for a minute but that's about it. It doesn't compare to walking through the shallows of Costa Rica and peering down into the reefs, actinics only make it more of a show by illuminating the fluorescent proteins.
