Hello Everyone, has anyone encountered tiny little insects living in your clay pebbles in your aquaponic grow bed? I have a an insect problem in my grow beds and I believe there are tiny little aphids and a kind of jumping little white insect that hide in the crevices of the clay pebbles. How do I get rid of them, should I clean my clay pebbles with hydrogen peroxide? I set up this grow bed about a year ago, I don't have a sump tank or a bio-filter, I think this might be the reason why I have the pest in my grow beds. Does anyone have any wisdom they can share with me?
