Does window screen block light?

I am using two layers of window screen, one underneath the eggcrate and one on top. People suggest to use either pond netting, which the holes were to big or screen net. So i got screen net. Now i'm thinking that it's blocking a good amount of light.

 

I would assume any solid object is going to block at least a little light. what are you putting the screen up for ?

 

it was suggest to do something because some said firefish would be able to jump through the holes of the eggcrate.

If this doesn't work i'm going to do the acrylic idea

 

that would be the way to go i made a lid for my 20 gal long out of it 1/4" but it kinda sags a bit heh i even hinged it and made a door it works kinda nice though i with i'da gone a touch thicker to prevent sagging as it suppords my lighting as well

 

only problem with the acrylic idea is i don't think it would be possible to cut areas for equipment plus the bowfront shape and i don't think my dad would have any tools to cut acrylic

So i think im stuck with eggcrate and window screen. I just don't know much the window screen will affect corals though. I'm hoping to get SPS down the road *not any time soon* so i don't think it will affect softies or LPS. But i just worry about the difference

 

If you are talking about like the screen for a window or door to keep bugs out, that blocks a substantial amount of light. Id suggest not using it. Especially 2 layers. There has been like 5 threads on this same topic in the past week...

 

yea the tank just looks dark to me, even with all for 4 bubls on.

I didn't even notice there were other topics of this this week

 

i dont knwo what kind of stores you have down there but up here i go to tap plastics they will cut the acrylic to any shape you want free, i think i paid like 20 $ for everything thats 4 nice hinges , glue , custom cut acrylic , handles , the whole kitten caboodle just be sure to go in with a drawing with dimentions and they can make things happen

 

never heard of the place, don't think w have one. The only other problem with acrylic is the salt creep

 

i havent had a lick of any salt creep on my home made lid >,< i get creep on my glass lid though
