bustah8 That looks very nice! Clean, simple and elegant.

iKine The bowing wasn't as bad as one might think. It just looked awful to me so I needed to address it.

So far other than that the stand, tank, and lighting are all up and running good. I put a nice dual 24" T5NO fixture in the bottom opening of the tank, and I'm in the process of working on a auto watering system for some plants I'm putting underneath.

driftwoodhunter Very good tip - bowing of the rods under weight would be a "Doh!" moment for me ; )

iKine I thought I would update a little on the stand.

I was having an issue supporting the weight of the light. Because aluminum is so flexible it was pulling down the rods to the point where I would lose some adjustment. So I came up with these.



The rod sits through the hole, and the wider flat side sits against the back of the tank. This holds the rods back and straight with the weight of the light on it. It also makes it so dependent on where i place the brackets (various locations vertically along the back of the tank) it gives me more adjustment to move the light forward and back.

I made these out of solid maple scraps at work, sealed and laquered them. You could easily make these out of almost any material, even thick cardboard. I first used scrap clear plastic lying around the house to make my template. Even those alone would have worked but I opted for something a little nicer.

I haven't put them on the tank yet, I'll get pics if I get around to it today lol.

iKine I made the stand 2 3/4" over sized front to back, and 1/2" over sized across the length. That gave me 1/4" reveal on the front and two sides of the tank. Also gave me 2 1/2" of space at the back to run all my wires, filter pipes, and light mounts.

In hindsight 2 1/2" was over kill, I could have gotten away with 1 3/4".

keithy ikine,

did you leave enough space for your tank to sit on? The holes looks like they are close to the inner side of the wood, which is where the tank will sit. Nice idea nonetheless.

iKine Sorry, I didnt mean to come off with attitude lol.

And the glue should be yea, but I didnt seen a point in taking the screws and brackets off. Once I have the shelf in the bottom (which reminds me, I have to messure it lol) you wont see any screws or brackets.

This time, I paid .30$ per foot, and bought two 5" lengths from work.

It seems you do know what you're doing, I was just checking. I missed the screw holes at first. The glue should be more than strong enough.

iKine I didnt even think to biscuit it! lol, I have a biscuit jointer and everything.

I just used the brackets to dry fit everything, square it up. I then pulled it all apart, glued the joints then reassembled it. After that, toe screwed it all the make it stay nice and rigid.

audioaficionado Did you use any softwood jointing such as biscuits, dowels, ect?

I've found the main purpose of screws is to hold the wood together while the glue dries LOL.

The light hanger is really nice though. How much did the rod cost?

iKine I could park my mercury on it ! its not going anywhere

Deffinately recommend gluing softwood joints on top of screwing. Screws can pull out to easy in the red cedar.

audioaficionado How's the racking resistance?

Can you get it to wiggle if you really try to?

I glued and clamped 2x6 redwood together for the corners and then glued and clamped mitered picture frame flat style 2x4 redwood for the top and bottom. I've got a 400# tank on it and it's still rock solid 27 years later.
