Hello all,
I recently set up a 20 gallon long tank.
I recently have had a brown algae outbreak on all glass and on rocks. There is also green algae (not cyano) on all the substrate. I originally transferred everything from a 10 gallon.
While moving over, I added a bunch of dead live rock that someone had given me on FB marketplace.
Since then, I have had zero nitrates and high phosphates ~0.25ppm.
If I had to guess, I am guessing the rock is leaching phosphates and fueling the algae that is eating up my nitrates.
How would you guys fix this? Is it better to dose nitrates or to try and reduce the phosphate with media.
I have 4 fish (2 clowns, fire fish and royal gramma) and a cleaner shrimp.
Thanks!
