View Full Version : substrate vs. mp10

01/21/2010, 09:53 PM
I was wondering what substrate people use in their nano tanks with an mp10. or if you have any other vortech pump, what sand substrate so you use? i'd like to possibly have substrate instead of bare bottom but at the same time have the substrate be nice looking(fair) yet not too small to make a storm.

Use one inch of medium grade argonite

I use a layer of 2" medium grade as well... It still blows around some but i run my 2 mp40 at 100%
