Where to buy Dolomite?

[FinalPhaze987]

My mg test came out a little on the low side (1000-1100 ppm) so im trying to track down some dolomite to throw in the ca Rx. Does anyone know where to find some that we can use in our tanks? I went to a local quarry which stocks it for sculptures and building, but the guy working there said the one they carry does have a whole bunch of other minerals found in it, one being copper..TIA

isn't that a mix of calcium and magnesium carbonate? If so, isn't that the exact same thing as ...onyx gravel/sand?

Does it work well to keep up the levels?

in a CA reactor it can, but it'll do nothing if just placed in the tank

You can get "Dolomite Lime" in the garden section at OSH (Orchard Supply) It's $10 for 25 pounds, or $6 for 5 lbs. Obviously the 25# is the better deal. I was gonna get some for my tomato plants, but it's too late to lime the soil now so I didn't pick any up. I'm not sure if it's "brown and scary looking" like the stuff Rich ordered online (I did a search on Dolomite in the forums and found some other dolomite thread"

Well, when you grow tomatos, depending on your soil, you might want to bring the PH up to the sweet spot for the plant you are planting.

Also, there is a condition that Tomato plants called "Blossom End Rot" where the bottoms of new tomato fruit are blackened, like it's rotting. The cause is that the plant is not getting enough calcium and so it's robbing the fruit from the tip of the fruit. It could be that there is not enough calcium in the soil, but more likely it's because the soil moisture fluctuates too much and the tomato plant is not properly absorbing calcium with its roots. In fact that's usually more the problem than lacking calcium in the soil, but I'm growing tomatos in containers so I thought the containers might be getting washed out. I think it's actually poor watering on my part (I use a drip system on a timer). Also it's too late to mix the lime into the soil, since the plants have grown into the pots. But I thought that maybe it might help. I'll do it next year anyway.
