Hey Everyone!
I've always been interested in aquariums my whole life and finally got myself a small JBJ 12 gallon nano cube to begin my adventure into this awesome new hobby. Needless to say, it's been quite a journey and a huge learning experience.
I've come across this problem that I've had for the past month or so and can't quite seem to shake it off. I perform weekly 25% water changes and all of my parameters for my saltwater are fine.
I've attached some pictures, but as you can see... On one side of my tank, I have this green film-like substance on the glass. It's been there for about a month or so and it seems to be contained and not spreading.
Also, beneath the surface of my sand bed, the coloring of the sand is turning light purple and small air pockets keep forming. I usually move the sand around with my turkey baster to get rid of the air pockets and the purpleish sand.. but within 24 hours it reappears.
I hope you can help this newbie out!! Thank you in advance!
