Lighting through a glass top?

[Doo]

I have noticed by looking at many pics that most people do not have their SW tanks covered...

Does this have anything to do with the light getting to the coral?

What about the fish how often are fish lost due to lack of cover?

I was thinking a simple 5mm single sheet (NOT the 2 overlapping/ slide type) glass top...

Any comments or thoughts would be great

Fish do jump, and many people have canopies or egg crate over their tank. Both those options allow for fairly open (sometimes fan-assisted) air flow. Putting glass over it will trap heat and limit oxygen exchange, and that's not so good. In addition, the salt splash and evap/condensation will (I'm guessing) make the glass opaque quite quickly, which will limit the effectiveness of your lights.

Hi Matt

When you say Egg Crate, are you talking about the plastick checkered type stuff (white plastic all squares) - where do you get that from?

Thank you!

i think it has a lot to do with more surface area expose to air.... supposed to be good for tank. "airgation" (sp?) something like that.

i ve lost 2 fishes due to jumpers, 1 was a mandarin and the other was a pearly jawfish and the jawfish is known to be a jumper. i just didnt listen....

I have a glass top on my cube tank & have to wipe the underside of the glass every day.

Having a Korallia pointing towards the surface probably doesn't help too much but it gets pretty opaque if I don't clean it for more a few days.

I'm getting a bit p***ed off with it at the moment & will change it for an egg crate pretty soon & live with the extra evaporation (the tank has an ATO).

Can someone post a picture of an egg crate and let me know where I can get it

You maybe get it at Rona? Home Hardware? Home Depot? Commercial lighting suppliers?

bump for the best eggcrate pic ever.
Very nice.
what kind of camera did you use?

I used the mighty Google Imaging Camera

(I'd never have 80's style grey carpet with coloured flecks!)

Eggcrate is good for so many things, I think most of us have a least a partial sheet in our garages

You can get eggcrate at any of the big box home improvement joints. You just need to ask for a light diffuser as most people working in the stores will look at you with crossed eyes if you call it eggcrate

I used to use it when I had a tank with a plastic rim on it.. if your tank is eurobraced it makes it a little trickier to secure to the top of the tank.
