Hi all

I’ve been battling algae the last few months which has ultimately ended with a Dino and now cyano outbreak. Could someone help ID which dinos I have?

Thanks 6CB6D5BE-E2BE-4F86-BB17-935702C02899.jpeg

Looks like ostreopsis to me, they are not nice. not hard to get rid of, but not exactly easy. UV and dosing po4 is a good start. What ive always done is skim heavy and dump the skimmer cut back into the sump to keep p04 higher, after they are gone cyano will come and the uv will knock that out too, but stop dosing p04. use lanthanum chloride dosed into a filter sock to knock the p04 down. walla... my whole process took roughly 6 days. ive done this 3 times.
 
i should have added, a series of small water changes for the nitrates. but when you do them, change 1/2 of what your changing out, say your going to do string of 10% water changes, do 5% wait 45mins to an hr and do the other 5%. If you change to much to quickly there is a likely hood of dropping nutrients to quickly and they can come back.

Thanks for the reply. I will need to grab a UV then if that’s the strain. I’m dosing P04 daily to get it detectable but I am also dosing nitrate as is its only around 5 if I dose and drops if I don’t dose. Do I want to be doing water changes in that case? I had read the water changes can make the issues worse adding trace elements to feed on?
 
move like amphidinium. May be small cell amphidinium. I can't quite nail the scale, but they look a little smaller and faster than large cell variety.
 
Its not ostreopsis
