Fluval Stratum or ADA Aqua Soil Amazonia
I have been reading up about both of them and don't know which way to go. I have stratum in my 10gal QT and I like it. But I have heard great things about aqua soil too. I would try it out. But I'm look at redoing my main tank that's 72 gals and ADA Amazonia is over $60 a bag here in Canada; the places that sell it is 3 hours away.
