i just have them hanging from the kids dvd shelf for now. eventually... if i stick with this lighting, i want to get a vinyl fence post, a couple endcaps and feed the sockets through from the inside and put the reflectors back on. then paint everything flat black and add some hanging hardware.

I got algae the first time I set up this small tank using 14W fixture only. Staghorn and BGA appeard. I reduce photo period from 10 hrs to 5 hours, the algae were gone. Then I found this work lamp idea and installed 14watts spiral bulb. I was not happy about it, upgraded to 27Watts and run 6 hrs. CO2 was set 2-3bps and carefully watch EI dosing.

After two weeks, the plants are thriving very well and pearling like crazy!!!

I'm planning to add fish in few weeks or after plants get robust growth.

On a side note my rotala just started to shoot up after the low top trim, can't wait till the l aromatica and reopens start to grow

Do you have a journal for your tank moose? I really would like to look through the progress you've made. It really looks great.
No, I wish I did start one. I just got this camera. Before that I had this really horrible cam that came with my $5 phone

My 40b is less than a month old. I had a 30 gallon just like yours. I switched from the Flourite black in the 30 to Black Diamond sand in this one. I think you may have seen that tank in another thread or two that we've both posted in. I really do like the 30 gallon size though. I bought that setup used for peanuts, but the tank was built in 1987 (said so right on the "Made By Billy" tag in the bottom) and there were scratches all over the glass and the silicone didn't owe anybody anything. Like many others, the bug bit and I just had to have what I wanted so I set out to buy myself a "nice tank". Well....

I was all bugged about getting a rimless tank. I spent weeks researching and decided that I could get that nice tank, but then I was stuck with the stand it came with, which usually costs as much (or more) than the already ridiculously priced tank. I don't have the space or tools to make my own any more. I definitely do have the skill - I used to have a full metal and wood shop in my basement. Envious amounts of Tim Tooltime. That was another life. Now I live in an efficiency apartment and those are fond but distant memories. So....

Realizing that a 50 gallon rimless and stand would set me back close to or over a grand I said "Petco here I come!" and drove directly over to their $1 A Gallon Sale! and bought me a 40 gallon breeder for $40. Found an ad on Craigslist for an Oceanic 70 gallon with stand (same dimension as the 40b) so I bought that too. That tank needed re-siliconing but I wasn't interested. Waay too big for my room. I dumpstered it. It was that stand I was after. It was off-pink colored pickled oak... I sprayed it with Krylon gloss black. Like a boss.

You know, sometimes our subconscious works in mysterious ways. This is one of those times. The science and the aesthetic decided not to argue for once. I might have been happier with a rimless tank, but somehow I doubt it. I would have had to put up with one of those fugly stands they come with and I would have had to remind myself every time I looked at it how dearly it came...

So, I was out $200 for the used stand, $48 for the tank (they tax you on $100 when you buy them at Petco!!), and $25 for spray paint, sand paper, and beer...mostly beer...

Sounds like exactly what my progression will be! I woudl love a rimless tank, but in all honesty I could never afford one, and would probably enjoy making something like yours more. I'm going with the black diamond in the next tank for sure, looks amazing. I start a new job next week, so maybe I'll finally have some funding to get the lights hung and a few things sorted out with this one.

Yes, the 40 breeder during the $1/gallon sale at PetCo is the way to do.

Hello!
Question, for a ten gallon, would two 13 cfl be sufficient for a low to medium light?
Thanks!

Get a couple of 13 watt LEDs instead. They are more expense (around $25 each), but will last longer and are much more safe to put in an open fixture over your tank:

Yes, it will be sufficient, if you have a fairly good reflector behind the bulbs. Otherwise it would probably take higher wattage bulbs. See http://www.aquabotanic.com/?p=1497 for more details.

I'm really interested in this cheap method of lighting my first planted tank. I took a look at the link that was posted earlier... http://www.aquabotanic.com/?p=1497

It doesn't say specifically how many bulbs to use other than 2 for a 10 gallon tank. I want to do a low tech, non CO2 tank. I have a 29 gallon... I'm guessing I should use 3 bulbs total at 19 watts each (so 60 watts at 2 wpg)? Or is that too much light?

It depends how you place your fixture, far or close from your tank that make a 60watts low or high light setting.

I have 41watts on my 5.5G that would be "7wpg". I placed it close to the tank that made it very high light.

Here's a good thread that explain it further in details.

That's a great thread which I just read. It doesn't really seem to help unless I had the exact same tank or a PAR meter. How will I know how far to raise the lights for the right PAR for a low light tank?
