It actually works best when sandwiched between filter media.
It also can be used in a reactor, but the tumbling speed must be very gently.

I put my "bag" in a simple HOB filter, sponge, then ROWA, then carbon on top.
I use 50g of the 100g jar (stuff comes wet). I am not sure how long it will last, we are only in week two, but I would guess, a month at most! Testing weekly for phosphates to determine this.

I think this is a "get what you pay for" thing, the absorption rate of phosphate is much better, had a bit of algae, just melted away in first week of use.

Can see no ill effects to any inhabitants, in fact, I thought my corals seemed more inflated than usual.

I will buy this product again...Got this tip from a guy in England, 650 litres and wow, absolutely pristine.
