Hey guys, new to reefing and to r2r, so I posted this originally in the wrong forum. I have some dino that I believe is large cell amphidinium. I have been trying to get my phosphates up as they zerod out and I ran a UV just in case it was ostreopsis, but can you guys let me know what type this is so I know whether or not to buy Si dosing and test kit. Thank you all in advance!
