SeachemPhosGuard Phosphate and Silicate Remover, 2 Litre

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

Great product just make sure to wash before use as instructed .

Does exactly what you would expect. It removes Phosphate and silica. But be careful with the dosing as it could strip all the phosphate out and make it hard for plants to grow as plants require a little phosphate to grow properly.

Good product when used in a reactor keeps phosphate out of aquarium

Maybe a coincidence but on the two occasions I have used it fish died a day or two later. Won't use again.

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

Sono contento perché rispetto ad un altro prodotto utilizzato in passato questo risulta molto più agevole nella sostituzione (il vecchio prodotto andava sciacquato per un po' perché doveva rilasciare l'ossido di ferro superficiale). Non ho dati "misurati" ma l'effetto sulle alghe nere tipiche di silicati alti sembra buono.

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。

Wish it was cheaper.

Product works! however this is my fault, but I wanted to warn fellow fish keepers. I was noticing a small amount of hair algae in my reef tank. So I decided to add phosguard in a mesh pouch and add it to my refugium. I didn't measure it thinking it didn't matter. I just poured 1cup of it into the mesh bag. Well we ran some errands and when i came back within 2 hours time all the fish were laying at the bottom and gasping for air. I put them all in a hospital tank and they all survived. I did a 30% water change and everything is back to normal. So be careful.
