Algae taking over

[michael.cser20]

I have this algae taking over and I have no clue why. It's brown and tiny little comps and it grows on everything even my sps in spots. I'm running gfo but it's not doing anything I don't know what to do. I have a feeling it's my rocks. They are very old. Extremely old actually but I cooked them way before I used them and the tank had been up a year and half now. My nitrate is showing around 2 and p04 is always 0. I have a pair of clowns and 2 pajama cardinals in the 75 gallon do I don't know where this stuff is coming from

CUC? Some snails may be able to knock it back some... Maybe some astrea turbo snails?

I got 10 of them

They don't seem to eat it either

How much do you feed? Light?

What are your tank parameters .. ??

I feed half a cube a day of frozen mysis. Ati 6 bulb on from noon to 10pm

Ph 7.9-8.3
Sg 1.026
Temp 77
Alk 7.8
Mag 1260
Calcium 415
Nitrate 2-5
P04 0

Looks like it may be dinos. does it grow faster after a water change?
Low po4 could be causing it. in my old tank whenever my po4 bottomed out dinos would pop up so I had to reduce gfo to find a good balance.

What test kits are you using ??
What are you testing po4 with ..?

Salfiert for all but all and alk with Hanna

I agree with #bdog4u2 think you need too raise your po4 .. try feeding a little flakes too your tank that should raise them

My tank has always ha 0 phosphate. This algae started when I added my old extra rocks back into my tank.

take out the rock and use a toothbrush and scrub them and also do water change to remove those as much as possible.

I do that weekly but it comes back. Idk what kind of algae it even is

What the issue is that you added new rocks. you created a small cycle again. So in theory you need to cycle your tank again. The bacteria need to colonize the rock and use up extra nutrients. Be patient and allow the tank to cycle with the new rocks. Running GFO will speed up the export but don't worry this is normal.

I guess I added that rock in beginning of April though. The algae was just on the new rocks but then it spread to the old ones too.

To give you an example i have a 700 gallon reef tank and I added just one dry rock the size of 12" x 12" from my old tank. The tank was fully cycled. Within a couple days I had brown algae breaking out all over. It took a few weeks for the tank to adjust and export nutrients. So you can see the effect of just one small rock in a tank my size can do. Now you have a lot smaller volume so the amount of nutrient load will be many times higher.
