Just buy it and be happy
Tried a generic alternative and huge regrets. The generic caused massive silica spike and of course tons of brown slime everywhere in the tank because of it. Absolutely 0 issues with this product and also 0 regret. I learned my lesson the hard way.

Good for supplementing liverock
First of all I would like to say that I live in Turkey and bought 2 of these 3 months apart. So Amozon has shipped this item to me twice and havent had any problem whatsoever due to shipping. So kudos to Amazon.The first block has been in my tank since July and I havent seen any disintegration or degradation. My ammonia was never detectable so i assume with the live rock in the tank its doing its job.
