Hi,

Limestone comes in may shapes, forms and composition. Aragonite and domilite are just two forms of limestone. Aragonite is mainly Calcium carbonate while domilite is a 60/40 split between Calcium carbonate and Magnesium carbonate. So when it does dissolve, aragonite disolves in to a Ca++ ions and domilite disolves in to Mg++ and Ca++. So...there is 60% aragonite in domilite (or so). But, I don't think a DSB will dissolve much faster than the rate at which magnesium or calcium is consumed -- in fact I think it is much much slower.


In fact, I would be more incline to say Domolite is better for reefing than Aragonite since Magnesium is leeched back in to the water column.

People have asked if domolite can be used in a reef before (check RC). Dr Ron and others seem comfortable with it. There are several people are using it too.

Anyway, I would try it if you are on a limited budget (like the rest of my little projects). Its like overdriving lamps...why do it if you can afford an HQI ? So, just keep that in mind. For me...its a hobby. I have fun trying to figure out why a DSB works and how come you need oolic sand to make it work. Is there a better way ? Cheaper way ? Environmentally friendly way ? What is necessary and what is ... just pure false information.

Say darren...don't you put domolite in your calcium reactor for magnesium supplements ? That is what I heard you have to do once in a while or your magnesium levels will drop too low and cause your tank to crash.
