Survey for "Updating the WPG rule (theory)"

[czcz]

Please post the following. Let's use what you can grow and your judgement for whether it is a low-very high light tank. With this in mind, past lighting set-ups are still usefull if you feel confident about the lighting level. If you happen to have >4" substrate or something weird please note it.

Tank volume
Tank dimensions LxDxH
Watts (please break down by lighting type - T12, T8, CF, spiral screw-in CF, etc)
Lighting level (low-very high light)
Notes

Here is an Excel spreadsheet that does Ozz's current article calcs for your for you (lumens/watt for each bulb can be changed in the bulbs book as necessary).

This will help in playing with formulas by using real-life tanks. Please leave this thread as data only and discuss here: http://www.aquariumadvice.com/viewtopic.php?t=72491 Thank you.
