Yes, I have had planted tanks for awhile. Have battled algae, mostly successfully, for over 25 years. Using organics (i.e., peat, mulm, soil - although I'm not partial to the potential mess with soil) in the substrate has not proved to be a cause for algae outbreaks. Jobes sticks have however, when disturbed. I would only use Seachem Flourish Tabs, if anything. With a sufficient topping to the peat - 3+" - the water did not noticably discolor.
