Dirt tank concerned with my play sand cap.
So my tank has 1-1.5" of aquarium soil along with a 0.5" silver (play) sand cap. It has MTS digging around. I'm concerned that I've gone the wrong way with the sand and that it will compress closing off the dirt to O2. However this might only be in regards to sand caps more than 1". I only have small fish in ATM so it might be easier to sort it out now.
Plants seem to be doing okay after 1 month and I don't have dirt breaking the cap even when I've pulled out a couple of plants. Am I worrying over nothing.
So should I just leave it and see?
Should I vac up a bit of the sand to have the minimum cap?
Should I strip it down and start again with gravel cap?
