We spend hundreds, most of us thousands, on rays but are quick to save a buck on SUBSTATE? Seriously? THE cheapest element of an aquarium?
NO long term effects of this sand that has been introduced to aquariums what? A year or 2 ago? So IF I poison my liver daily for 2 years and am NOT dead then that means I will NEVER die form it?
I CAN'T be only one that thinks this is rediculous......

I use "t" grade black and love it, have used tan, and white "s" grade too, it is good stuff..
It's funny you mention this. DB junkie;3915306; said:I talked to Estes and they coat their sand as well. When I explained that ray autopsies are turning up disolved coatings on sand grains the guy said their sand coatings hold up to acid. Its an autumotive grade polymer that they use. Well further discusion about the rays took place and the end result was him telling me "I'd use 100% natural sand in this case". "No, we don't sell any sand that is 100% natural"
I'm not gonna risk it. BUT on the same note I don't know what the hell I'm gonna do for sand.![]()
