@Randy Holmes-Farley I would like to spur diatoms as I hear they are good for feeding pods, but I run UV for fish parasites (as well as to continue to fight coolia). On Mack's Dino group they advise against running uv if trying to induce a diatom bloom, but I understand different organisms need different contact times. I've asked on R2R before and on the Dino group but cannot seem to get a contact time for diatoms. Do you know?I personally would not use organic carbon dosing to try to eradicate dinos since they may well consume the organic perfectly well.
IMO, you want to boost competition, and making sure N and P are readily available, and potentially dosing silicate to spur diatom competition is a good plan.
