hi,
im in the process of converting my 75 gal. community tank to african cichlids and i wanted to know which caribsea substrate to use as the buffer? my ph out of the tap is 7.5 and i have read on this forum that a lot of you use some sort of buffer either as the substrate or in the filter. i was out shopping today and the LFS had 3 types of caribsea substrates: aragonite, argamax and crushed coral. in your opions, which one should i use, they are all pretty much the same price so that's not an issue. im going to be putting it in the filter. thanks

thanks,
so is there a big difference in the 3 products or just personal preference? i plan on putting a bag full into my c-360 canister to help buffer the water, along with the rift lake recipe if needed. Again, im just starting the conversion to cichlids from my community set up and my ph is pretty stable at 6.8, which is where its been for the past 3 years. thanks again...

yes, i would be putting it in a bag/stocking and placing it in the filter. i wanted to know which would hold or buffer the ph better. im converting too pool filter sand next week, so is it better to combine the caribsea with the PFS and mix it into the substrate or have better control and just use it in the canister? thanks
