As a long time fish keeper, im curious about the nutrients in aquarium water. Ive run some tests using it to water a strawberry patch and had mixed results. I watered only half the patch and half the patch I was watering died. The plants that survived grew noticably larger than the "natural" side both plants and fruit. Not sure if it was the nutrients, extra water, or extra space from killing half. I also have no idea how npk numbers relate to ppm, but I know my tanks are 10-30ppm nitrate. Idk if thats high or low for plants, but id love to see the results, im too afraid to try myself. Though I have grown many gorgeous aquatic and semi aquatic plants in my day and was very close to setting up an aquaponic lettuce and tilapia farm just to see if I could.
Cool thread ill be following this closely. Also when you talk about not adding oxygen to mixtures, are you talking about adding bottled O2 to nutrients? Adding an air pump and stone seems very common but I dont see how that could cause any issues unless im missing something. I have seen pressurized co2 used but not pressurized o2
