So I've had this 180g that I picked up from craigslist back in March but I haven't had anytime to clean it or set it up for the last 8 months. I'd really like to get it up an running before the new year and I finally have some time this holiday week to spend some quality time with it.My stupid question is will I break anything if I crawl inside the monster to clean it? It's sitting on its stand and my arms won't reach everything. It would be much easier to use some elbow grease if I were inside the tank but I'm not sure if that would be a good idea or not. After 2 preganacies, I'm just over 160lbs; will it be okay for me to crawl around inside as long as I don't jump up and down?
