Dinoflagellates, or what?

Hi everyone, this is like my first thread on this forum, so I might have posted this in the wrong category, but its titled "algae" so maybe not.

I'm pretty sure I have a dino problem, I just finished a 4 day blackout, it knocked out most of it on the sand, but now it looks like I'm getting some on the back wall of my cube. I am also unsure if the brown algae that is growing on my sand bed is actually diatoms, it seems too dark to me. Can someone confirm that these are indeed dinoflagellates, and what are my options to getting rid of them for good. I understand this is gonna be a struggle :/

Tank has been set up for 2 months, fishless cycled since mid January. There are no fish in the tank, I made a noob mistake and introduced ich, so they're in hypo right now. I have 0 Ammo, nitrite, nitrate and phosphate. But I bet I'm getting false readings on the nitrates and phosphates.

I told myself before I started this thread it wouldn't be long, lol its getting too long. Here's some pics:




Diatoms or not?


Thanks in advance for any advice!

 

Looks to be cyanobacteria.

 

You think all of it looks like cyano?

This is probably the first (and last) time I'm happy to hear cyano lol

 

Yes it does to me. Just siphon it up, increase your flow and try to keep your pH up.

 

Thanks, and should I keep the lights on during the day like usual?

 

it looks like you have both cyano and diatoms which are different from dino's and easier to get rid of lol

diatoms feed on the silicates in your water most times they will go away as the silicate gets used up

cyano is a different story just follow 2in10s suggestion and you should be good

 

Whoo hoo! I'm so happy now, I thought this would be a massive battle against stupid Dinos.

Thanks guys! Hopefully I can get rid of this stuff. I did order some phosban to see if it would help at all, planning on trying it out in a filter bag in the media basket.

 

Media basket? As in cannister filter? If thats the case be careful, if there is too much flow in that filter it will pullverize the phosban and render useless and maybe even blow it back into your tank

 

No, the water from the tank overflows to the back and flows through the basket. It's not that much flow at all, but I don't think it's too little either

 

As long as its not blasting it I think you'll be ok
