A very handy spreadsheet for calculating light penetration in your tanks. - APE - Aquatic Plant Enthusiasts

I found this wonderful spreadsheet created by essabe over at PlantedTank.net and thought I should spread it around for all to enjoy. Another poster, S&KGray, made some fixes to it and here is their final work for you to download into Excel and use. Very handy and, pardon the pun, illuminating. The directions are straight forward and easy. I have found that my own tanks sit in the Bright Lit category pretty consistently.

This will be a great budgeting tool so you can purchase just the right amount of light and makes it easier to leave that old fashioned watts per gallon rule of thumb behind and not buy a PAR meter and measure every fixture that takes your fancy. Definitely a good way to prevent buyer's remorse and second guessing.

Share & Enjoy! I have attached the spreadsheet as a *.ZIP file for your convenience.
