Pockets of sand turning black beneath shallow sand bed (pic)
Hi, I noticed the other day that the sand in one of the back corners of my tank has turned black in pockets beneath the surface... I've heard of this happening in tanks with DSB's, my sand bed is quite shallow (1-1.5 inches tops; the pic is very zoomed-in)
Is this something I should worry about, and can I vacuum the spots next time I do a water change? I usually try to vacuum my sand bed whenever I do a change but this spot is in the back corner so it's been neglected.
Thanks for any feedback you can offer
