Dinoflagellates

[Rafaelpadro24]

Hello everybody, just looking for some guidance. Had a dino issue due to my nitrates and phosphates bottoming due to my feeding qty and running my skimmer and refigium light 24 hrs day. Corrected my refigium schedule and began feeding a bit more also dosed nitrate to bring numbers up. I did a sand bed vacuming through a 5 micron filter in a canister, blacked out the tank for 3 days and dosed microbacter7 also installed a UV light.Well after 3 days turned my lights up to 20% and mostly blue and began to monitor the sand bed. So far I have not seen any presence of dino appearing. It's been a good 2 week and I like to know if I could ramp my lights up. Enclosed are pics of my rocks and sand in regular ambient light. Any feedback is greatly appreciated.
The tank was setup in August of 2022.

What are your no3 and po4 now and how long have they been at this levels?
Also how old is this tank?

Are your nitrates and phosphate up at appropriate levels now? Dinos are present in every tank in some form. The bad ones you had are not gone just getting out competed now by good bacteria. I don't see why you can't start ramp up as long as numbers are stable.

No3 is a 7.5,po4 is at 0.14 tank us going on 9 month.

Did you use a microscope to id and makes sure none are present?

Sorry but don't have a microscope

I’d say you are good to go. If you see any Dino’s while you are ramping back up turn the UV back on.

It’s 50-50 then you may or may not have any dinos who knows. Maybe turn the lights on more intensely and see what you got. If they come back, then I would invest in a microscope.
