Was planning setting up my new tank ( http://www.aquariacentral.com/forum...7-new-5-gal-window-tank&p=2818184#post2818184 ) with dirt capped with sand or gravel, but then my LFS recommended Fluval Stratum and I've read a lot of positive things about it... Would it be a good cap for dirt? Or would that be too much? If so, which would be better for the plants, dirt or this?
Thanks
