Hello everyone, I just got the old ebb and flow goin again. It is a homemade system with a flat bottomed flood table and because it is flat a small amount of water is allowed to collect at the bottom of the tray (about 1/4 inch). I was checking my ph and noticed some little shits floating around in the bottom of the tray. They looked like Fungus gnat larvae. Since I have a little soil thing goin on too they probably came from there. Anyway, I was interested in any tips from others who have had similar issues. They arent causing any problems yet and I dont know if they will have anywhere to live (other than getting washed down into the res.) since i'm using hydroton as a medium, but I dont want to take any chances. Has anyone else had to deal with this?
