Hmm,
So according to Wright's comments below then I guess my cheap PVC cut
into
1/2 with al tape inside probably won't really work. = )
I guess the ahsupply would work the 2 t5 tubes I guess if I can only
fit 2
max inside the one reflector then to mimic 2 tubes of a CF?
Well I'm looking at this reflector (besides the ah supply one) this
one's
specifically for T5 but for one tube only
http://www.reefgeek.com/products/categories/lighting/104051.html $20
And acorrding to their 'output' comparison link it seems like the
reflectors
help....
Have a glance :
http://www.reefgeek.com/product_images/sunlight_supply/
t5_reflector_output.j
pg
And
http://www.reefgeek.com/product_images/sunlight_supply/
t5_reflector_inaction
.jpg
I was also looking at this reflector :
http://www.aqualuxlighting.com/39ultra.html for $14 but I believe it's
for
one tube only also =)
Hmm then there's this stuff I guess I could use inside a 1/2 DIY PVC
reflector :
http://www.bustan.ca/product_detail.asp?menuID=4&SID=29&PID=120
Mylar reflective film?
Well that's all I found for reflectors off the net for now, if there's
any
other recommended sites for t5 reflectors please let me know,
otherwise I'll
continue to do some more research =)

Shiny aluminum looks great but stinks for reflecting fluorescent lights
(except for the far blue and UV).
The AH reflectors are shiny aluminum, but with a dielectric overcoating
that raises reflectivity dramatically from the original 85% that is
typical for pure aluminum. Roof flashing and other non-dead-soft alloys
are probably a worse.
The screwing you get with aluminum is probably worse than the simple
15%
loss, as quite a bit of useful light may involve hitting the reflector
more than once in most designs.
Hey, it is better than white paint, but not really a lot. The aluminum
tapes I have tried are quite a lot worse than plain polished Al, BTW.
If you want to line a hood I suggest you find some of the silvered
mylar
materials that feature reflectivity well over 95%. 3M Silverlux was
once
discontinued, but I still see variations on it for sale around the web.
Forget plain aluminum or aluminum tape, if you want efficiency. You can
likely do better with potato-chip bags or cut-up CDs.
Wright
PS. If I was using twin-tube T-5 CFs, I would not hesitate to buy the
AH
reflectors. They are cheaper than anything I have tried that was
comparable, and a pretty decent optical design. [Not ideal for
single-tube T-8s tho.]

Beware that potato chip bags will disentegrate into little flakes of
plastic after a while. This creates a big mess in your tank. I
found out the hard way, and just wanted to offer a warning.

This will be a subjective experiment since I have no means of actually
measuring the light.
Any old camera (digital or not) has a light meter built in which will
give you the accuracy you need.
Just set a fixed aperture that puts the shutter speed at 1/60 sec
(aperture priority mode). Install the reflector and measure again. A
shutter speed of 1/120 sec would indicate the light output has doubled.

I used to live in Providence, RI while I was in college and there was a
great
little fish store on Wickendon St called Aqua-Life center, but they
often
had
species I couldn't find elsewhere, and if they didn't have what I was
looking
for, they could get it for me. They have a website:
http://www.aqualifecentral.com/ They certainly had more fish species
in the
store than on the web last time I was there a couple years ago, but
they
have a
decent plant selection (for a LFS). The fish on the web are probably
just
staples they have most of the time, and the harder-to-find fish will
vary.

0.5 kg is $50 for ACS grade (which is fine) or USP pharmaceutical

Arm and Hammar baking soda, 75c a box and weekly 1/3 water changes.
Looks
like baking soda is the clear winner, and if you do your water
changes, the
Na+ buildup is neglible for the plants and probably beneficial for fish
unless you have really hard water already.

The hydroponics.com franchises sell two kinds of reflective mylar. The
regular one doesn't stand up too well but the ehat and water resistant
one
will work and also has a claimed 95% reflectivity.

Yeah that's the regualr mylar that doesn't work. You need the heat and
water
resistant
stuff.
