PMed :)

This is the same stuff I was talking about lol

I haven't read through all the posts, so forgive me if something was covered ...

I like eggcrate
I have seen mesh-covered tanks before and don't like the salt creep I see on them

My eggcrate, after 10 months, has no salt creep at all
I will put up with whatever loss of light there may be :smile:

That's something that concerns me too. I haven't read anywhere about mesh getting salt creep but egg crate accumulating salt creep. This is causing a pain in my head :sad:

From my observations, Salt creep comes mostly from bubbles popping at the water surface, if you have lots of that, you're going to get salt creep regardless of what you put on top of your tank. For my 20g with all hang on skimmer + aquaclear, I get bubbles from when the water falls back into the tank, I see tiny drops of water fly around from the popping bubbles when I take my glass cover off and the salt creep on my glass cover for that tank is a huge pain.

However, for my 5g zoa/ric tank with egg crate on top, I have no bubbles popping near the surface (as there is no equipment other than a powerhead) and there is no salt creep at all.

Now from my personal experience with Eggcrate, it does reduce the light somewhat but what bothers me the most is the grid shadow I get on my sandbed as my 5g is only 10" tall.

Yap I can see bubbles popping all the time. :cry:

Why don't you just go out and spend the few bucks on a sheet of eggcrate and try it before you take all the time, money, and effort you'll spend on making a mesh cover ?

With your small tank, one sheet of eggcrate/light diffusor will cover it for, what, >$20 ?

And you'll have a bunch left over for other stuff

Give it a try
I love mine :wink:

I don't have any problem using that but people say that fishes can still jump through the holes. So many schools of thoughts just for one top :sad:

1/4" eggcrate is no different than 1/4" mesh ................... as far as hole size goes

Is there 1/4" egg crate??????? I thought all are like 1/2" or something that we use to put frag plus in.
