Blackwater Extract

I have a 10g planted tank, my water i think is a little hard but with DIY Co2 i have a constant pH of 6.8. I currently have schwartz corys, honey gouramis, and probably cherry barbs or neon tetras. Is it advisable to use Tetra's Blackwater Extract? or is it more trouble than it's worth? Does it allow pH fluctuations by softening the water?
