I was cleaning out my convict breeding tank a few days back. I sucked on the gravel vac to get the siphon effect started. Well I didn't suck it hard enough (man, this is starting to sound dirty)
. The siphon bubbled a bit then stopped. I failed to notice a collection of brown water trapped in the lower part of the hose. Then I sucked again, much harder then last time.
I spent the next 10 minuets hacking and coughing brown water out of my lungs. I'm glad the bucket was beside me cause I almost lost my supper.
Lesson learned:
If you fail to start a gravel vac in your first try, empty out the water before sucking on the hose again.
