We always try to empty our black and gray water tanks before heading home to our storage. At times it doesn't always work out and we end up leaving the tanks half full, no more, and put the rv in storage. It is not there for too long, 2 months max. It is in storage in Miami, not a cool place in temperature. We always drop in the blue packets of tank deodorants every time we dump and fill up again with 1/4 of water. Is it bad to leave the black water tank 1/2 full for 2 months in storage?

Leave raw sewage sit for two months? I don't think so.

Not something I would do, but depends somewhat if half full is mostly liquid, or lots of solid waste. I doubt the blue packets would do much after 2 months in the heat. I do try to always keep some liquid in my black tank, even in Winter storage, rather than let it dry up. After a good rinsing, I'll add quality anti-freeze, that won't evaporate, and helps lube the valve seal.

No!!!
A buddy of mine did that and ended up with a petrified layer of cement like stuff on the bottom of his tank after a month of sitting. It was VERY hard (and nasty) to break up and flush out.
You want to drain it completley before storage.

2 months doesn't seem that long
Boats leave it in longer than that
Why not try something like Rid X?
But what do I know. Most people tell me i'm full of ..it anyway lol

I've done it on accident before and not had an issue. I would not do it on purpose, but, uh, **** happens.

I saw a trailer one time at a dealer where the owner did not dump his black tank after his last camping trip. I do not know how long it had been since his last trip. The holding tanks are vented to the outside, so over time the liquid in the tank will evaporate. When that happens the residue in the tank turns into a solid block of poop.

I see that you live in Miami, I would be very careful about how long it sits.
