Just go to Walmart and buy black tank chemical in a bottle and be done with it. No mixing, no mess, no fuss.
If you do a little research here on this forum, you'll find that:
Black tank chemical in a bottle does nothing but mask the odor if (or when) you have a malfunctioning system and the odor of the black tank seeps into the rv. It does not clean the tank of residue left over after draining, it does not promote any type of resistance to future residue and will not do anything more than what plain old water will do.
The laundry detergent used with several gallons of water during traveling will indeed wash out the inside of the tank and insure all solids will be flushed out during draining. The water softener has two fold results. First it will soften the solids making it easer to drain and secondly, it will coat the inside of the tank making it slippery so that solids and tp won't stick to it.
Black tank chemicals are just waste (no pun intended) of $$.
