okay I started a batch today- 50 lb sac milo, 6 small yeast packets and 1 lb sugar and plenty of water.had it bubbling in less than 45 minutes.
Does anyone add anything else? dead fishes, stink bait, liver , wife's tuna casserole,or anything?

you can add anything from ground up minnows, dried up stink bait, or some fish tails.

That will work for you. Nothing needed,other than a week or so.

I like to add some choped garlic helps really bring out the stink

After my last fish fry some one left a modello dark beer. I don't drink so I added that to the milo. Next trip caught 62.

your good with just the milo.
I try to use a 50/50 cracked corn and milo to make it go further. The cracked corn was cheaper than milo by a good bit last year.

just let it sit as it is.
BUT! if you just "have" to add something
After its ripe (before use)
Add a quart of cooking oil to the bucket and mix it well.
It makes for one nasty/stanky oil slick that drifts for miles

40 oz of Steele Reserve Malt Liquor Beer. . Also check your water level every other day you want to keep the grain covered with water.

Ram urine.

Drippings,cooking oil,MENHADEN OIL

Keep it covered with water and wait. All that other stuff won't make a dang if you let the maggots get into it. They'll take the stink out.

No need to add anything else here is some info on chumming for catfish.

Personally, I'm a big fan of the Ram's Urine. Gotta lot of stank to it. But, if ya can't get Ram's urine, you can always invite a couple buddies over for a case of beer and take turns freshening up the milo yourselves............ LOL

how long do I keep it covered in water? first week/two or always?

All the time. just need enough water to cover the top of the grain like a few inches. If not you will starting growing wheat inside the drum. I have seen this before with Catfishsalsa's grandfather. His neighbour didn't put enough water over the grain and a month later it was wheat growing. Hope this helps.
