Calling All Ei People

[Themuleous]

Well as some of you may know I'm going to write an thread on nano tanks, but whilst doing my research and having read Georges nano tank journal I have decided to reinvent the wheel and try to find 'rule' for lighting tanks that works on lumen's per surface area rather than on WPG, as WPG can be so misleading as to be almost useless.

Here's where you guys come in, in order to work out some sort of guide I need to find out what lighting people have on their EI tanks, just EI tanks please as this is a high-light 'rule'. I would be really grateful if people could post very simple stats about their tank as shown below.

Size - Please put the dimentions not just 20G
Lighting - please list all the light tubes you have over the tank, their make, wattage, kelvin rating if you know it and size. If anyone knows the lumen rating of the tubes that would be invaluable, and will save me having to look all of them up!

That's really about it.

If anyone has some advise/experience with this sort of light guide please let me know, I might be wasting my time here, but as George recently suggested lumen's per surface area is probably a more accurate way of assessing how much light you need for a given tank.

Thanks

Sam

Use watts if you don't know lumens. Tube per tube watts are similar enough in terms of light output, at least enough for a "guide".

Sam, you can see my stats in my nano thread.

Ok, will do anyone else gonna post?

 

[-=Joel=-]

Not sure if this is much help:

60 x 20 x 20

3 x 150W halide bulbs (10k each)
4 x 54W T5s (4k each)

 

[Themuleous]

Thats perfect Joel cheers. Do you know that make of the bulbs?

 

[-=Joel=-]

sadly I think they are just non brand ones Lol.

Has nothing on the tubes except the 54W and cool white. Sorry not much help however the bulbs are very cheap

Can you enlighten me as to what a Ei tank is??

 

[Themuleous]

Thanks people

Kiwigirl EI estimative index, have a read of the pinned article at the top of the planted section for more info.

Holds approx 210 litres

3 X 38W Interpet Triplus T8
1 X 38W Arcadia Freshwater T8


I've always thought that lumens is a poor way of measuring light output for plants as it mainly measures the human response range ie yellow-green leaving out the reds and blues.

I never knew that. Watts could be the better option then.

If you want to get technical then take a look at this very good article - http/www.aquabotanic.com/lightcompare.htm

Thanks James. I've browsed that link before but obviously didn't absorb much info!
