Pulverized limestone VS pulverized dolomitic limestone

Hi everyone,

I have used Pulverized limestone as a substrate in the past but now I can only find 'pulverized dolomitic limestone" is it the same thing?

I always used dolomite for substrate in African cichlid tanks, so I can at least tell you it's aquarium safe.

Never had it like that. It was white gravel actually for aquariums if I recall and rinsed clean very fast. It was 30yrs ago lol. kept the PH high and added other minerals that made Cichlids colour up beautiful. It seems from what @wvned said, it might not be the best choice for salt water anyway.

It is a dust used in farming for soils to raise pH and add magnesium
The dust works faster

I grew up on a farm, we used to spread pulverized limestone on our pastures but I don't remember it being that dusty, I remember legit grains of sand coming out of the spreader. I mean at two dollars a bag it was worth a shot, now I know that substrate doesn't work.

I'm open to other suggestions, Im trying to avoid aragonite because I have to get 300lbs of substrate for this tank and at almost $2 a pound thats gonna be rough.

Take a look @ Carib-Sea, they have choices.

I THINK I put 2 or 3 40 pounds bags of crushed coral in the 240. 80 -120 pounds
BRS calculator says 153 pounds for a 225 (26x71) 2 inches deep with crushed coral.

why so much, 300lbs?

$25 for 40 pounds and 4 bags should do. If you are balking at the substrate wait till you buy lights.

I like burrowing fish and have a massive LTA that will give me a 6 inch sand bed in the 230

I have the tank all set up and ready, lights and all, I have the water waiting in my water tanks on the boat that i collected 10 miles of shore just ready to get pumped, I have all my live rock from my smaller tank that will be added to this tank
