My calcs are roughly one to two drops per gallon per week - does that sound in the ballpark to you guys?
What's the expected colour in the bottle, by the way?
Davros - the duckweed killer, right?

Your calcs seem spot on. I've got Seachem Flourish Comprehensive and it's a dark, murky liquid - think seaweed extract. The smell's pretty strong, kinda like the ocean.

Thanks for the confirmation, and the heads up on the smell and color of Seachem Flourish Comprehensive.

Davros, the infamous duckweed destroyer

I'm sure a few folks around here would be super interested in your duckweed elimination methods

I'm still figuring out the magic trick, but duckweed's been a non-issue for me. Guess it's the crazy water movement, but even the bacopa's given up the ghost. Only the hardy grasses are hanging in there, which is why I'm looking into this new fertilizer.
