Orko, I wasn't directing that comment at you.
The original question by the OP was "What would happen if I "Never" vacuumed my gravel. Then he states that he didn't do it in 4 months. Thats not really "Never". It's more like 20 weeks.
The fact that you didn't do it in 30 years is great. You are probably a very good aquarist.
I don't really vacuum mine, but because I use a reverse undergravel filter and it has been in there for almost 50 years I stir it up and suck it out to make sure it doesn't clog because a UG filter needs circulation. If it were not for that, I probably wouldn't vacuum it either.
