Algae on sand bed

[Rafael nyc]

First I want to thank all that have helped me out.
so far my corals have been doing fine, but Im starting to get a lot of algae on my sand bed and on the rocks. My clean up crew is loving it. I think it’s my phosphate levels
cal 450
alk 8.3
sal 1.025
temp 79-80
ph 8.2
mag 1350
pho 0.26 before the refugium they where 0.98 only have it for 2 weeks
I have a protein skimmer
just started a refugium
uv sterilizer
any advice

Any pictures of the algae?

There are a lot of causes for algae to develop. Phosphates could be the reason, but could also be diatoms due to high silicates.

This type of Algae is dusty and appears on the sandbed.

I think it's so hard to say...here's the one parameter that's causing my problem and if I fix that, it'll be fine and my problem will go away. Just doesn't seem to follow in a lot of cases. I think keeping parameters where you think they are optimized for your set up is absolutely required for success. Issues will not go way if parameters remain bad. But it doesn't always follow that issues will go away once you correct either.

Looks like diatoms to me. Probabely due to elevated silicates. Hoe long gas the tank been running for?

sandsifting goby takes good care of this
