Warren:(posted 8556 days ago)You should be able to fill a tank with 2 rolls of 120 in no more than 15 seconds. Try tilting the tank about 30 degrees to one side to let the air trapped in the tank to escape. If you don't allow the air to escape, there won't be enough room in the tank for the chemicals. As the tank gets nearly full, you will have to decrease the angle somewhat in order to fill the tank completely. Doing it that way, you should be able to fill it much quicker. You'll also find that the tank will empty more quickly if it isn't totally inverted. Just pour the chems out with the tank at an angle less than total inversion. Practice a little by filling and dumping an empty tank a few times with water.
