Canopy weight

[steveoutlaw]

I'm going to be building a canopy for my 210g this weekend and was wondering if there is anything that tells how much weight the tank will hold. Anybody have any ideas?

steve-

 

i don't think soo... but i used pine 1x2"s on my canopy, and 1/4" plywood, and even with the lights, i can easily lift it with one hand. that's on a 90. i would imagine you'd want to go as light as possible... i've seen some dooky big canopies out there though.

 

i have a ridiculously heavy canopy on my 58, and i don't like it.

Lets just say that Euler column buckling would give you an exact answer. However, we don't even have to go that far. One of the dominant terms in the column buckling equation is the modulus of elasticity. Wood gets an 11, Glass 72 and Steel 190+. Suffice it to say, your stand will collapse before your tank due to an excessively heavy canopy.

Actually when pronounced it sounds like oiler.

Yes, but he didn't tell you that the stand and canopy are going to be made out of titanium.

 

Can you tell that I'm ready to go home for the day?

well hey sure, wiki said that, and now i feel stupid.

 

but it was alllmost funny.

 

come on beltway, we're ocean flo raffle buddies. cut me some slack.

who isn't at 4:19 pm on a gloomy wednesday.

I'll cut you slack on it, I was rotfl at that. Of course I didn't know the correct pronunciation either. Did I mention that I'm ready to go home?

Ok, well........now that we're finished talking about the Oilers....wait, they don't exist anymore....oh well.

 

I'm making the frame of my canopy out of pressure treated 2x2s and I'm going to have the front and sides be 1" oak. I'm going to leave it as an open top to help with airflow. This sound OK?

[ErikS]

Oak? Planks or Oak ply? In either case you can likely skip the 2x frame. Just a rectangle with open top & bottom. Put a strip across the top for mounting the lights.

 

You only need a frame if your were wrapping in 1/4" material.

 

Just use a strip on the inside to support the box (can hide the upper frame with the overlap).

 

Easier & lighter.

Pressure treated 2x2s are a bit excessive but nothing wrong with that. But I would definitely not leave it open top. I actually just built a canopy last weekend and have been researching this stuff like crazy. You want a lid on it to help catch more light. Paint the inside of the whole thing white. If you have great reflectors and you don't mind looking at light leaking out the top, then scratch that and do whatever you want, because it's probably a negligible gain.
