phoshpates

Hi everyone, Basically I left testing for 2 weeks and had a mag/cal and alk drop so I’ve just fixed that then i was looking and in the last 2 days one of my clowns disappeared fully with no trace, (the tanks only 4 months old) so I moved all the rocks looking for him, now my phosphate has gone...

Hey, I found recent AF product - Anti Phosphate - https://aquaforest.eu/freshwater/products/af-anti-phosphate/ It's relatively light color, so it does not seem to be a ferric hydroxide related as most of reef dedicated products are. I wonder - what could be the ingredient and why isn't it...
