The most common questions regarding the Zeroedge Aquarium deal with evaporation, salt creep, cleaning and touching.
Evaporation and salt creep were major problems when ZeroEdge first came to market about 4 years ago. But since then the problems have been worked out. Today, evaporation ranges from 1/2 gallon to about a gallon, depending on lighting and size of the aquarium. It's really a non-issue, especially when most reefers have dosers, dosing pumps, etc..
Salt creep is going to occur on any salt water tank. Most salt creep build-up occurs from very small air bubbles that fizz and pop at the waters surface. The splashing and surface agitation from the return adds to this. The design of the ZeroEdge makes it virtually impossible for salt creep to occur. These tanks have little or no salt creep due to the steady stream of overflowing water and gentle channeling of water to the sump filter box. Of course you will have salt creep in your sump, jsut as any other tank.
As far as cleaning goes, all tanks have to be cleaned. With this tank, yes you may want to clean both sides with a acyrlic safe pad. But nothing is cooler than having snails help you clean the outside of your tank!!! That's not possible with a regular tank.
Don't touch the tank!! LOL! It's a riot, it's gonna happen. The glass like appearance of a ZeroEdge invites people to touch..they just can't bellieve what they see. It comes with owning an ultra-cool tank!!!
