| MJ1200 works great in my 5g bucket. I use a magnetic holder to hold it on the side and it makes a great flowing wirlpool. I use the same "clean" MJ for filling the tank and refiling the bucket from other mixing tanks. I use a separate "dirty" MJ and bucket for removing water from the tank. I have a tunze 6025 for mixing in a 10 or 20 gallon tank for mixing. |
