what is everyone using. I kinda let it go to long and I have a lot of calcium built up on the bottom and the pump.
I know vinigar, but is there something stronger, or am I better of buying a new can. lol
I just use the vinegar....Mine needs to be cleaned again too I have a 45G can so I use almost a gallon of the vinegar...fill it over half way...or where the "buid up" ends.....and let it soak over night
works every time
