strange algea issue

[robert teseo]

all tank #'s are fine. no3&po4 are both 0. cheato is growing well in the fudge. in spots I have some type of brown/green algea. in spots it's stringy, on the snail shells it's brown/green with bubbles.and it's not all over, only in spots. any ideas to chase?. tried chemiclean with no difference.

How long has the system been setup?

You do need .01 to .03 phosphates and nitrates between 3 to 5 ppm for the corals to grow beside your Ca, Alk, Mg

If you can post a picture and would be helpful so we can get some more eyes and help on this.

Could be dinoflagellates. A pic would help. Siphon as much as you can out of the tank when you change water. Lights out for a couple days might help also.

coming up on 3 months. I never did get a brown diatom issue. I started with real live rock and sand from tbs. all corals are clean and growing well

What is your nutrient export method? are you doing water changes and if you are are you using r o d i water? And How often?

 

[robert teseo]

ro/di yes and at least 10% weekly

if fact, the other day I drained the fudge, cleaned it and rinsed the cheato out

staring at the tank, I realize almost all the algea issues are on the left side of the tank, the right side is almost clean. the set up is a 75 with 2 wav heads. on the right, it's on the back wall pointing forward and of the left it's on the side wall, pointing across the tank. is it a flow issue? I moved the left one to the back as well.i,ll see after a few days if theres a change.
