k9outfit Posted June 19, 2006 Report Share Posted June 19, 2006 So, how about: to do away with BGA, you need to add enough plants that the plants use up all the nutrients and starve the BGA (and/or other algae) out? You need fast growing plants (fast growing requiring more nutrients than slow growing), and by adding NO3 you promote maximum growth. You also need to add enough plants that you tip the scales in their favour, and the plants' nutritional requirements excede the BGA or other algae's. So, indirectly the addition of NO3 does affect the BGA and other algae, not by poisoning it, but rather by promoting excess plant growth and starving it out. BTW, where do you get the NO3? The few aquarium fertilizers I have on hand all vociferously state they "do not" contain NO3. The closest I've gotten is Nitrogen in stuff for my roses....

jvision Posted June 20, 2006 Report Share Posted June 20, 2006 Best bet to find NO3 is look for KNO3 at horticulture shops, hydroponics shops, or... if you can find Stump Remover at a hardware store, that'll do the trick, too. Quote Link to comment Share on other sites More sharing options...
