I have a 55 Gallon with a 30 Gal sump that has about 10 gallons in it. I have been having trouble with the Calcium levels, cannot seem to get it above 320. Some suggested that my Magnesium levels are low so I ordered a Mg and Alkalinity tests. I have since stopped adding any calcium until I get a handle on the parameters but I want to ask

I was told I can use epsom Salt (which is Magnesium Sulfide) to bring up the Mg but if I need to bring it up several 100 PPm I need to watch the increase in Sulfide, some site suggest even a 600 ppm increas in Mg with epsom salt would not have any bad effects from the sulfide, I want to know what others who have done this think?
