How long does one bleach an empty tank that had hydroids? How much bleach?

¼ cup per gallon should be enough, and I'd let the tank circulate for perhaps a few hours. Bleach fumes can be nasty, so I'd consider emptying the tank and moving the contents outdoors for any treatment. If there's a lot of organic debris in the tank, adding more bleach might be a useful idea. A chlorine kit could quantify the rate at which the bleach is being consumed.

Thanks Bertoni! It's already empty, outside, and circulating fresh water. Will start the bleach tomorrow!
