We have it in my daughters fowlr tank.
It's only been up a few months but we love the different look of it. Needed to change up from white sand being this is our third tank in the house.
Don't judge me. LolWith TANKED playing on the Tv
Apparently, Nature's Ocean Bio-Activ Live Aragonite provides "enhanced" buffering abilities. Can anyone confirm this is true?
Has anyone used this stuff? I can't find out what the grain size is.
Sorry for the crappy quality but I've had my tank on black sand for about 3 months and haven't had any problems. Corals getting great from small frags (can't see it in the picture but I can post close ups if you need more proof). Same as any other sand so far
Who here has used black sand? Particularly either of these types:
Hawaiian Black (0.25 - 3.0 mm)
Indo-pacific Black (0.25 - 5.0 mm)
I am thinking about creating a tank with a Lembah Strait/Sulewsi Indonesia theme. The sand there is mucky, black and made up of volcanic matter.
I know the main issues with black sand are the lack of buffering abilities, as they are not calcium based. Has anyone every tried mixing it with some calcium based substrate? I was thinking about mixing it with some of the Caribsea Special Grade Reef Sand, to provide some calcium buffering.
Another issue is the grain size which has a wide range, up to 5.0 mm which is much too large. Could I use a strainer to sort out the extra large grains?
If you have used black sand in your tank, POST A PIC! I want to see what it actually looks like in real life.
