I'm using it in my 55 and like it. It clouds the water if disturbed - even after multiple rinses, and is lighter than Eco. It will get heavier after being in the tank awhile. I've heard it is the same stuff as SMS.
I have oil dri, which is supposed to be similar to SMS(if not the same), and one of my hg or kh dropped to less than 1. I'll have to check again later, but should I worry about itIt will steal all the KH out of the water............
Turface Pro League (check the link in my previous post for a local supplier) is inert. It's cheap at $13-$18/50# bag. And because it's pretty light weight material, 50# goes a long way. It took about 75# to put an avg. 4" deep layer in my 120g tank (48"x24" footprint). And it's relatively fine grained so delicate plants like HC have no problem rooting in it.I need a good substrate which will not change water chemistry, does anyone know of one?
plants will grow in turface under your conditions. (i have low light, no c02/excel). it is, however, very light.Thank you everyone for the advice. Is Turface Pro League a good option, I mean, will it grow most plants well in a medium light/DIY CO2 situation? I like the price...and there is some suppliers in the general area. I actually do not mind spending more money, BUT I cannot have it changing the water chemistry, and it sounds like pretty much all of the commercially available substrates do.
