PhosGuard, 2 L/67.6 oz.

Uso questo prodotto da anni un po' caro

Buen producto

Reliable and doesn’t break down in a chamber. Can take decent flow without tumbling.

アメリカから輸入している為3週間ほど待ちましたが、コスパ良いです。

This product was well packaged and delivered earlier than expected, it's great at helping to control the phosphates in my reef tank
