Paint

[snowmansnow]

Ok stupid question:
I want the back of a new tank black. What do I paint it w? Krylon?

Krylon is ideal. I used Rustoleum Ultra Cover put on with a brush for the first 2 coats then used a foam roller for a total of 7 coats. Worked well.

I saw some of the MRC sumps used black vinyl and it looked nice. If you know anyone at a sign shop that might be able to hook you up.

I have used Krylon on several tanks and all look good!

Same here.

I have used spray on Krylon Fusion on tanks not setup yet and a Rustoleum roll on paint for a tank I already had setup. Both worked fine. I like the look of the Krylon better but I think that was because I used a satin finish but used a flat finish on the Rustoleum.

+1 on the Krylon

+2 on Krylon

Got to through this out there AA did a study on painting the back of tanks it showed a loss of light spread and par on the painted sides. Seams that un painted glass reflects more light back in to the tank increasing par values.

I would agree with the Krylon Fusion spay paint. Much better finish. At falos, I would expect that it isn't so much the fact it is painted but the color it is painted. Black obsorbs almost all of the color spectrum (which is why it appears black to us). White would reflect almost all of the color spectrum but wouldn't look very nice. I split the diferance and whent with a light blue. To me, it makes it look like the entire ocean is in the background.

That information was presented at MACNA XX in Atlanta by James Fatherree. I actually attended that talk, but it has been a while. I had just joined the ARC at the time. Painted backgrounds greatly reduced PAR vs non painted ones. I'll post a link to the article or presentation if I can find one.

Painting will change the 'index of refraction' of a glass surface.

Without giving a physics lecture here, I can see where the light striking the painted surface might be reduced.

Color and wavelength(s) would be secondary considerations.

But we have missed your lectures. :yay::yay::yay::yay: hehehehe Nice to see you back now and again.

But if your not going to clean the back glass anyways you mine as well paint it.

Plasti dip it

Thanks Rich! It's good to be able to spend a little more time on the boards.

Yea, I never would have thought of this..

One savior I have with this current build is that I'm running an ATI SunPower 6x38w over a 40gb with will be PLENTY of light... I'm even concerned that it may be too much in a tank that shallow.

HOWEVER... thats good to know for other larger builds.....

How does a coraline cover back glass effect par levels?
