I feel I should make some comments as I’m likely the only one here who has worked on one extensively.

I think once the gimic wears off… it leaves you with some really obvious disadvantages.
You’re now dealing with algae on both sides of the glass.[/quote]
Totally worth it. If you ever think about buying a tank twice as large as your current one just stop yourself… you’ll be cleaning twice as much!

You will have salt spray/splash like you have never imagined. [/quote]
Actually have less salt spray. Think of all that salt spray on the rim of your tank… find the rim on a “zero edgeâ€ÂÂÂÂÂÂÂ. These tanks have less salt creep then any of the other tanks I have ever worked on.(I’ve worked on hundreds)

Every bit of dust, debris and bug will end up in your tank.[/quote]
It’s called ATO, these builds or DIYS projects have been around for awhile.

Could be true, but I have never seen a bug in a zero edge. Regardless I’ve never seen or heard of it being an issue.

New challenges and restrictions for attaching lighting/hardware and their power supplies.[/quote]
Real reef keepers love a challenge. How many of use have tried sun coral? How hasn’t wanted to keep an elegance coral or a long tentacle plate? Isn’t that one of the many drives for us to get SPS? Frankly the most discussed and popular topics on the hobby are typically the challenging.

They’re great for when you need to catch someone’s eye like a display booth at MACNA, just not long term IMO.[/quote]
Is the last thing you want your aquarium to do is be eye catching?
[quote=“moliken, post:4, topic:2338”]
my worry is that as beautiful as they look, one scratch from a coral or a scrub and the all round near invisible flow is interrupted and it will look crappy.[/quote]
Is something you would need to be careful of, but that being said one of our clients who has a zero edge has had his tank “rescapedâ€ÂÂÂÂÂÂÂ(rock scape redone) many times and it still looks beautiful. This was one of my biggest concerns with them, but the more I work with them the less I worry.
[quote=“moliken, post:4, topic:2338”]
others not thought of like airborne fish, snails and hermits, maybe nems, climbing out[/quote]
The walls are too slick for hermits to climb. The same client aforementioned has three anemones in his tank, none have ever gone over.(and as far as anemones go what about your overflow box or power heads, they could die any number of ways in a classic reef tank) Fish on the other hand is an issue just like any other open top aquarium.

sweet. you’re raffling off an infinity edge aquarium. I knew it.
this is legally binding. ;)[/quote]
I thought you were
[quote=“RCA, post:3, topic:2338”]
never too enthusiastic about the idea.[/quote]

[quote=“Nemmy, post:18, topic:2338”]
I wonder how snails like it, you know they are going to want to go over the edge and down the outside of the tank, causing some odd overflowing.
I wonder what the sump is like underneath, your going to have to fish snails out from it all the time.[/quote]
Snails are not a big problem at all. If they were to make it outside they would just hang out in the moat around the outside of the tank.(unlike in a standard aquarium where either a dog or cat would eat them or they would just dry up and leave a pleasant smell) They would never reach the sump as there are sponges on the drains in the moat.
