ID help

[Diazcm]

hello all, can anyone help me ID this type of algae I got here? It’s growing on my sand bed and starting to grow on my rocks. At first I thought it was diatoms but when I test for silicates Test kit shows nothing then I though of Cyano treated for Cyano and nothing has changed. Also I’m noticing that my corals are slowly losing color. Any idea what can possibly be going on? Thanks all

Water parameters
Cal-450
Alk-8.2
Mag-1500
Nit- O.00
Phos- .02
Ph-8.0

What type of lights do you have and what test kits are you using? I'm curious if it's a false reading in nutrients and or spectrum change in bulbs (if not using led). Had a similar issue years back with old halide bulbs and a broken TDS meter on the RODI.

I have radions G3 for lights. For test kits I use.
Red Sea- Cal,Mag, and Nit
Hanna- Alk, and Phos
Salifert- silicates

I believe my TDS meter is working fine, it’s only 2 yrs old and got it with the BRS 6 stage system.

Let's get more eyes on this. #reefsquad any algae experts out there?

I don't want to say it but... Dinos?

Looks like dinos to me too.

First step is get your nitrates up. Anywhere from detectable to 10ppm is likely fine. I use sodium nitrate for this.

I get algae similar to this when I bottom out my Nutrients. As soon as I dose back up they go away. I try to keep mine at 5-10 Nitrate and .08-.1 PO4 personally.

I don't want to derail the thread but why is it that dinos appear in low nutrient systems? If the ocean has 0ppm at all times what causes this to happen in tanks and not reefs?

because in the ocean it's not a true 0, but our systems can actually hit a true 0, because they are closed.

Also there are dinos in the ocean, lots of places in fact. There are a ton of strains and kinds and they all react differently to different conditions.

the MOST common we deal with are the ones that thrive in low nutrient environments, but it's not the only one. It's definitely the best place to start though.

Pristine reefs have very low nutrients, but unlimited low nutrients. The corals, algae, etc use up .01no3 a current delivers .01. Our tanks dont have that luxury. Use up whats in the tank have to wait on you to replace. Not an endless volume of water.

Thanks guys I'll make sure to stock my next tank heavily

I leaning this way, especially with nutrients as low as they are

Phosphate block. Nitrifying bacteria die off. Other organisms take over.

Looks like a couple things. One on the sand one on the rock.

Are either of them just slime when you pull them out ?
The stuff on the rock appears to to have structure like an alge.
