welcome to the 6105 club :-)
Not sure that you really need that front grill though. I removed mine after noticing that it just ends up collecting junk that I have to clean. They are so strong there is no way anyone is going to climb into the powerhead. Unless of course you unplug them for feeding, in which case you should really be using them with a controller as all of them have a feed mode which will jerk the propeller to scare out anyone who has climbed in there during the feed pause :-)
