FISHLESS CYCLING Aquaponics HELP!

PH 6.0 won't interfere with fishless cycling.

If you already have nitrite and nitrate just less than a week into the cycling, you are making really quick progress. I didn't get either readings until several weeks later on my first try. Have you used any bacteria seeding? Live bacteria product such as Tetra SafeStart or a piece of filter media from well established aquarium can do such trick.
