We use a small plastic funnel I purchased at Auto-Zone or any auto parts place. Make sure you're using real 6% sodium hypochlorite, not the cheap dollar store trash. The strength will be on the label, in small print. If you only can buy the 3% then you'll need twice as much. Clorox is the real thing. Unscented, of course. It smells bad enough already.
