Mysterious tank issues

[Sonny Alaniz]

I went on vacation for a week and got back to a huge outbreak of dinos or diatoms that started to eat up all of my nitrates so I decided to remove half of them to slowly get rid of them
but my Duncan started to bleach and shrivel up. I moved him to another 2 month old tank 30 minutes ago which also has this dino/diatom problem.
How do I get rid of these algaes taking over my tanks without hurting my corals?

Can you post your water chemistry parameters and length of time stable?

At night, does it disappear, then reappear when lights on?

Temp 77
nitrate 0
Phosphate 0
Alk 10
Calcium 410
Magnesium 1230
Ph 8
The tank has been up for about 4 months
The algae doesn't go away even at night it glows red

I have no idea what to do but im pretty sure my Duncan is almost all dead except for one last head barely hanging on
I ordered a uv sterilizer and put it into the tank with the Duncan and the algae is somewhat going away
I have no idea what to do for my big tank though

With 0 nitrates and 0 phosphate your corals are starving to death and dinos are thriving on the little available nutrients in the tank. You need to correct your parameters. It looks like you have cyano along with dinos in one tank.

its been 5 days since i tried this my sand bed looks alot better

each of the 3 times i had dino outbreaks were when i was on vacation and came back to bottomed out nutrients.

i usually get a fam member to feed daily when i'm on vacation but it wasn't cutting it (life happens), so I run an auto feeder when i'm out and about.

my tank is much happier if i keep NO3 over 5 and PO4 above 0.02.

Algae actually thrives under low nutrient systems. Some systems can Handel more nitrate than others. I keep mine at least at 20-30 ppm and phosphate at 3-5 ppm I have never had an outbreak with my levels at this, until recently my nitrates dropped under 10 and I have a bit of hair algae.

Phosphate 3 to 5? Is that a typo? Do you mean .3 to .5?

Ya typo .o3-.05
