Okay I don't want to be flamed on my stupitidy on some aspects here
So every day after I get in from work I normall go straight to my tank stick my hand in and pull algae out
(I have a planted tank) Without turning the heater off
but Lastnight I was setting a Raid 0 on my pc with two Raptor drives so ignored the tank,
Eventually I look at the tank and thought "hmm the heater don't look normal"
So out of the normal I turned it off and stuck my hand in to check it.
Only to find it was cracked and filled with water.
Could have had 240V through me and I'd no longer need Gel for my hair
Only conclusion for it to crack is an Air bubble must have been caught under it after it was ejected from the filter outlet (lesson learned in more ways than one)
only thing that has suprised me is the DAMN SNAILS DIDNT DIE
p.s no fish were harmed in the making of this as they are in a different tank
