White algae?

[Gordon3883]

Hey everyone,

I have a problem I'm trying to identify, about 4 days ago I noticed this white/transparent algae or bacteria growing on my rocks. I'm not sure what it is. I am new to the hobby and I have a 30 gallon tank which is about 4 months old. It'll somewhat come off with a blast from a turkey battery but it not easily. I've done 3 10% water changes. Just trying to figure out a solution. Any help is appreciated!

Parameters:
Nitrate: 3-5
Phosphate:0
Ph: 8
Ammonia:0
Calcium: 400
Alk: 8
Salinity: 1.025
Temp: 79

How's the flow in your tank?

It's good I have 1 circulation pump that gives good flow throughout the tank plus the filter. I've tried putting the pump directly facing the algae but did not see any results.
