What do you mean what is the best way to remove it? It can't be foamed in anything. When doing builds with any working parts you need to make sure you have anytime access to it. Do you have an access? If not you need to make one.
Well since it's foamed into the background and it doesnt work anymore making an access wont help anymore so now I have to remove it. and i was looking for a way to do it without totally destroying my tank.
