WillMcK Posted December 28, 2020 Share Posted December 28, 2020 I've been doing some research trying to find out the difference between these two. I'm getting confused and going down the rabbit hole of aragonite vs. crushed coral and the calcite vs. aragonite forms of calcium carbonate... I want to bump up the buffering capacity of my tap since it comes out at 2dKH and a pH of 7.0-7.2. I also would like to increase my GH since my tap is pretty soft as well at about 2dGH. Rather than dose equilibrium and alkaline buffer with every water change, adding cc or aragonite to my canister filter seems ideal. So my question is...is there a difference? Ideal pH would be no higher than 7.4-7.6 since I want to keep bolivian rams, black phantom tetras, any corydoras. Thanks! Link to comment Share on other sites More sharing options...
Paul Posted December 28, 2020 Share Posted December 28, 2020 @WillMcKit's 6 of one a !/2 dozen of the other. They'll both do the buffering you need. Link to comment Share on other sites More sharing options...
WillMcK Posted December 29, 2020 Author Share Posted December 29, 2020 So are they are the same thing? One won't raise my pH and KH higher than the other? I have a bag of aragonite on hand but wondering if I should get true "crushed coral" instead. Aquarium Coop is out of stock at the moment and the internets seem to indicate there is a difference, but what that difference is...I can't figure out. Help me obi-wan @Cory, you're my only hope...

Paul Posted December 29, 2020 Share Posted December 29, 2020 @WillMcKThey do essentially the same thing Crushed Coral is a coarser material with pieces of coral & shell. Aragonite tends to be finer. They will both make your water harder and increase your pH. It's your choice on which one you want to use. Link to comment Share on other sites More sharing options...
TheDukeAnumber1 Posted December 29, 2020 Share Posted December 29, 2020 @WillMcK I'm in the same boat as you. I've been using aragonite in my tanks with success but would also like to know if there are any significant or not differences between the two. Hopefully someone here critically compared the two and can chime in. 1 Link to comment Share on other sites More sharing options...
