I am setting up a 55 gal w/future 29 gal sump. I am going through the diatoms stage and am having another kind of algae that is brown/black and stringy. Also, my sand smells. I guess u can possibly describe the smell as a low tide smell but a lot stronger. I haven’t recently tested water but I should be going to the pet store tmr.
Here are some pics of the sandbed.
Any ideas what could be causing the smell?
