@FLFishChik I’ve used BDBS before and although I love the looks when it’s clean, I hate it when it’s not. Unfortunately you can see all of the poop,food, mulm, etc. This didn’t really make me want to get rid of it. One day, Cory mentioned that although it could used, it could give (my goldfish) any sand sifters tiny mouth ulcers. This was the deciding factor in removing it. I did buy a small magnetic separator in order to remove anything unwanted, but it became too labor intensive, so I just use pool filter sand.
I also know that the ACO trips to Peru illustrate how our substrate doesn’t need to be silky smooth. Personally, it’s more of an issue if the fish actively sifts the sand, more than anything else.
Now for the record. I grew Val and dwarf sag with no issues. I popped in 2 ACO root tabs every 30-45 days and we were good to go.
@nabokovfan87 I’m honestly surprised that there isn’t a go to brand for true black sand. Estes makes an excellent black sand, but it’s expensive.
