Alright today trying to take a few better pictures just to be on the safe side. Any feedback welcome. Also got a video with some movement.
I appreciate that! Do you have a particular thread for treatment?
Thank you!I'm sure it's on the big dino thread in several places but it's pretty easy to summarize. Dose silicates (water glass or something like Sponge Excel) to produce a competing diatom bloom. Keep nutrients elevated with NO3 in the 5-10 range and PO4 in the 0.06-0.12 range. Dose phyto and pods to help compete against them. Additionally some people use H2O2 at 1ml/10 gallons of display volume once a day. I have not done that as I have large colonies of zoas and they in particular seem to dislike peroxide.
Prorocentrum and amphidinium are usually not an easy/fast fix. It takes time to get rid of them. UV is not effective with them and is not recommended.
