Air trapped under substrate
Forgive me, I'm new to planted tanks. I Just setup an aquarium, and after filling the aquarium I noticed air trapped in the substrate. I can see trapped bubbles where the aqua soil rests against the glass. I left it for a few days hoping it would resolve itself, but I dont see that happening. Can this be a potential problem ? How should I resolve this if it is a problem ?
And one more thing. My aquasoil is leeching an extremely high amount of ammonia. How long will it do this ?
