Can you still get enough light with opaque tank covers?


I am just starting on my tanks. Before I decided to do NPT tanks I had opaque plexiglass I got for free cut to fit all of my 5 gallon tanks (for bettas). They are brightly lit even with the opaque plexiglass. If I use low light plants doing a Walstad tank will the plexiglasss have any negative effects on plant growth?

"Opaque": o·paque [oh-peyk]
1.
not transparent or translucent; impenetrable to light; not allowing light to pass through.

It would be really hard for anyone to guess without seeing them. It really depends on where the tanks are, for instance if they are near a window and get sunlight. You could try just a couple of anubias to see how it goes without spending too much. I wouldn't even bother with a "system" like Walstad, just whatever gravel you like the most and low light plants such as anubias and crypts.

I joined the forum yesterday and I suppose this might be my second question. "Welcome!" I am planning to backlight the aquariums as well as overhead them. I have to use leds to avoid overloading my circuit breaker. I will post a picture of my set up later today. There are no real plants in the tanks yet so hold the sarcasm when you see some dayglo plastic plants in at least one of the tanks. I have 12 5 gallons tanks to do and I will be doing more that are not covered by the opaque glass.

I think the word the user was looking for is translucent. It's my guess anyway. I don't know the answer to the question, but I doubt anyone would bother lighting through anything truly opaque.

Welcome to the site Sophia, If you could post a picture of your light diffuser and your setup in general it will help people give you a better response. It may be more efficient to line the tanks up and hang a fluorescent fixture over them as opposed to lighting each tank individually.
I haven't posted pictures here yet but i looks like they can be posted directly from your computer as an attachment when you post or you can also use an online photo hosting site like photobucket to post pictures as well.

Here is a portion of the set up with picture of the tank cover. Since the plexiglass was given to me the covers cost $6.00 to get cut vs $10.00 per cover that is the direction I took when I first set up these tanks.





My current light source is one of those round metal clamp on lights you can get at the hardware store with a screw in full spectrum bulb. I am contemplating other light sources I particularly need to go with led due to the age of my home.

From the photo what I think I see is a translucency to these lids. I think you have a misunderstanding of what opaque means. A photo of the specific lid held up the the light source might give us a better idea.
