So, I was messing around with a black light earlier and remembered how cool the glowfish were under them. Of course I go up to the tank and shine the light right over the water but I can't really see the fish as there is a green haze all over the tank as soon as the black light hits...

!!!

Then I thought, well, the only thing I'm doing differently now from the last time I tried out this neat little party trick is dosing ferts. Checked the Easy-carbo under the light and nothing... hmmmm...

Headed to the fridge, dug out the Flourish Comprehensive and viola! Icky green fluorescing liquid! Glad to know that there are in fact nutrients in there and its not just snake oil!

On an informational note, I guess we now have a colorimetric way of measuring how much fertilizer is in the tank and when its about ready for another dosing... Its been 3 days since I dosed and I've got a good amount of plants... if its cool enough, I'll post a pic of the tank right after I dose... fingers crossed!
