I've had some folks mention that the price seems a little high compared to other bio media.
It's really one of the least expensive options when you consider the amount of useable surface area by volume.
Just to compare it to Ehfisubstrat Pro, it takes about 5 times the amount of Ehfisubstrat to match MarinePure in surface area.
In other words, the 2 quart box of MarinePure Spheres ($34) is roughly the same amount of filtration as two 5 liter boxes of Ehfisubstrat pro ($59.99 each on foster/smith).
