I've been wanting to get some chaeto to throw in my tank to help me achieve better water quality. There's some on Ebay for cheap, but for standard shipping costs. Does chaeto need to be shipped next day air? Or is the standard shipping okay. I'm going to start dosing vinegar to help with my nitrates, but I also want to add some chaeto to further enhance the water. I'm afraid of the standard shipping but don't really want to pay 37 dollars for overnight.
