Great article on the use of lime! I have been using lime for the past 4-5 months in my 55 gallon reef. I use a float switch in the sump to control the amount of kalk/makeup water that is dosed into the sump. I would guess that about 1-2 cups of kalk is pumped into the system when the switch is activated. This is for makeup water, so it runs 24/7.
Here is my question - after about 2 months use of lime/kalk, when I clean my pumps and powerheads, a hard, calcium type residue forms on the pump shafts and sometimes on the pump magnets. Also, this forms on the heater.
Is this just something that goes along with the use of lime/kalk, periodic cleaning of pumps, or am I dosing the lime incorrectly - maybe too fast? My alk stays around 3.5 Meg/L and my calcium is in the low 400's. Thanks for your help!
