hi,
I have used natures ocean sand. I love it. Its bright white with flecks of pink. I have used this is 3 tanks. over the past 5 years.
HOWEVER, I do not buy into the "instant cycle" they claim to have.
heres my experience...I used natures ocean to "instant cycle" my tank. Then i added a few small fish, one week later...ammonia through the roof 8.0+ all fish die
your right to be skeptical. its too good to be true.
besides if you read the back fine print of the package...
it states that you should properly cycle your tank one month before adding fish...
so there it is.
personaly i love the way it looks, to save $ use dry sand as a "base" and top dress with natures ocean.
if its the "instant cycle" your looking for, its a NO GO.
-oozy-
