okay i have a slight alge outbreak, it is brown alge and it is only on my rocks, now it isnt all over but only on like ledges of indivual peices, now i use ro water and my phosphates are at .01, i am going to try cutting back on my lighting schedual to see if this works, now my question is this, does this type of nusance agle feed of atinics? so say if i cut my mh time from 12 hrs to 9 hrs and left the atinics to run the 13hrs would that be okay? or do i need to cut that time down as well.????? thanks

Need not worry! How old is your tank? This brown algae is actually brown diatoms which is very normal for your tank in the cycling process! You can siphoned it out with a turkey baster and add a few snails and a detritvore kit from Indo Pacific Sea Farm or Inland Aquatics HTH

It will disappear as fast as it appeared!

that is what i thought but my tank is 1 year old, and i am surprised that this is still happening, maybe it can i dont know

hmmm if your tank is a year old it should be fairly matured, unless you are going through a mini-cycle for some reason. What and how much are you feeding? Have you had other algae problems recently? What kind of corals are you keeping? a 12 hour halide cycle does sound a little long to me, cutting it down a little couldnt hurt. Algae will not use blue light so the actinics arn't really a contributor. Have you tested the output of your RO with a tds? Maybe you need a new membrane? the diatoms are taking up nutrients from the water, so cutting the lighting could help, but you need to eliminate the excess nutrients somehow.

hmmm ive had the unit maybe 3 months or 4
how often do you change the memberane

 

[mikeMersot]

you shoudl be fine with only 3-4 months, I have been using one for nearly a year and I have horrible water ranging from 600-1000 on the tds meter. Mine is nearing the end of its life now, so I doubt it is the membrane. how large is your bioload and what kind of skimmer do you use? also what is your feeding schedule?

everything sounds of to me, you may want to cut down on feeding a little until you eliminate the algae, but I definately don't think you are overfeeding, although I feed a lot less, once every 3 days, but all I have currently is a regal tang and sweetlips blenny in a 75. Seems like you've got a pretty good setup going there, so this may just be a fluke from a mini cycle or something. Adding a fuge with macroalgae in it would help too. I would just siphon it off and keep the flow high where it is growing, that should take care of it.
