mineralized soil bubbles?

2412 Views 5 Replies 5 Participants Last post by  prBrianpr
Did the mineralized soil process about two months ago (thanks Aaron!) and my plants are doing better than ever! The only odd thing I've noticed is if I push on the soil, I get a few bubbles that come out of the substrate cap. Is that normal? All water parameters are good, fish are doing great, plants are growing really fast with great color.

This is normal. I have the same bubbles also. Sometimes I see about 15-20 large bubbles in a successsion. Wonder how they stayed under the gravel.
