Neat!
I'm glad to see that you got your sig line worked out. I think that'll help quite a bit.

I'm 98.67% sure im not violating any rules now. i took my banner out and www.oregonaquadesign.com is my home page not my store. i need to sell some stuff so i can get money to become a sponsor then i wont have to stress over it.

p.s. APC i love you guys but it would be really helpful if you had all your rules posted somewhere. i can find some here or their but nothing really about sigs.

The store looks great! I have a couple questions...

#1. - why did you decide to go with the white dosing syringes? IMO, the usefulness of the syringe plummets without being able to see exact measurements. If you had difficulty finding the clear marked ones, maybe try a medical supply co. We use this company at my work, just a suggestion.
#2.Do you have any idea what size tubing a zoomed 501 canister filter uses? Its not specified in the documentation,and i can't find an answer online. the disconnects are an awesome idea, and I'd like to get some.

Again, i think what you're doing is very cool, and I look forward to watching your store grow.

Good luck!

1. The white syringes where ordered with the hopes that their would be a way to measure on them. Unfortunately my hopes where dashed! They still have some cool uses but as for dosing purposes their pretty much useless. I am getting some nice clear ones soon probably put my order in today actually.

2. I have no idea what size the zoomed takes but i will try to find out for you if worse come to worse i can send you some 1/2" and 5/8" hose to match it up to what you have.

I finally found the right syringes. and got the rest of my inventory in.

I am still trying to get a way to do a discount for forum members but Im not thinking its going to work because i dont have the right account with my server.

I want to thank everyone for the great ideas, and i hope this all works=0)

Here, http://www.sciencestuff.com/prod/Chem-Rgnts/C1296. , is something else that might be good to add to your store. I have never used it, but it seems that adding this to ordinary white latex paint makes it a high reflectance white paint. I don't have a feel for how much of this stuff should be added to a quart of white paint or to a pint of white paint to make it worthwhile. This, www.usu.edu/cpl/PDF/Barium_Sulfate.pdf, indicates that adding 1/2 of a pint of barium sulfate to a pint of white latex would do it, but I'm not sure how many grams that is. Just an idea.

I have been watching the mylar thread

from what i understood the concentration would be best at less then 50% for durability purposes. i think im going to have to test this with a light meter soon to see what works best for our use. lol as soon as i get a light meter and learn how to use it.

didnt you do par readings and find that foil worked better the mylar or white paint?

newbie314

try the mylar with the white backing. I'm wondering if that would the best of both worlds.

The foil did work a little better than white paint, but I only used a single coat of aerosol white, which apparently would have a reflectivity less than 80%, vs. the good stuff with about 95% reflectivity. If that really does make that big a difference, the white paint would be better than aluminum foil. But, it is so much easier to use paint than to glue foil to the inside of a fixture it seems that a high reflectivity paint would be a good product for our DIY lights. I admit I have no idea at all if anyone would buy any of the barium sulfate at around $15 for 500 grams. I probably would, if not now, then later.

You could get really creative and mix it up yourself, then sell pints of the mix. But, only after doing some testing. There is, or used to be a Kodak High Reflectance White coating that was widely used, but I didn't see any dealer for it in google. But, that was not water resistant.

I did some more research and calculating, and it looks like 500 grams of BaSO4 mixed with a pint of latex paint would give about 55% paint 45% BaSO4, which should be durable enough and should give enough reflectivity improvement to be useful. I'm planning on buying 500 grams of BaSO4 and a pint of whatever cheap white latex paint I can find at the hardware store and trying it out.

The experiment I would try is a small box enclosure with a single CFL bulb mounted in it. I would first paint the interior with plain white paint, then with the BaSO4 loaded white paint, then glue some aluminum foil inside, and possibly glue some mylar inside. All would be tested with a PAR meter with the meter sensor directly under the bulb and off to one side of the bulb, at various distances from the bulb, from about 3 inches to about 15 inches. That should give a reasonable evaluation of the effectiveness of the various reflectors.

But, the only place I have found to order the BaSO4 is the one I linked above and they don't tell you what the shipping cost is. I will have to phone for that on Monday. Making the simple box enclosure shouldn't cost me anything nor take very long to do. I may even already have a pint of white flat latex paint. It should be an interesting experiment, too.

This is off topic, so I will do a new thread when I get going on this.

Edit: I just found an ebay store selling this stuff as a high temperature oxidizer for fireworks??? So, since the price was right, $5 for 10 ounces, I just bought some.
