Brown algae?


In Memoriam
My rocks which have been added 4 days ago is getting a yellowish coloring, some parts brown. Is this normal? Tank is about 5 days old now. I did a water change of 1 gallon with distilled water. Tank is 10 gallons. Only live sand and live rock.

nitrates .5 ppm
phospate 0 ppm

did you test for nitrites? i would think they would be rather high. at any rate, be strong! it will pass!~ but i do think you should continue the water changes. 1 gallon a week should be fine. i've never heard about not doing water changes. if this the thing to do now please say so.
