Thanks! I wiped the brown stuff from the acrylic and so far they
haven't come back in 2 days. The water is still clear and I just put in
some polyps I bought.

One more dummie question, do polyps retract their soft 'arms' in
shippment (mine is bought from ebay and shipping took 2 days)? This
morning I started to see some red and green things growing. How long
will they grow to be like 1inch long?

Thank you.

It is brownish, closer to the 2nd o color of "Google" logo above. Is it
harmful?

Thanks!

You say yellow, but is it more of a golden brown?
Golden brown would be diatoms.

Yes I have a 24x7 protein skimmer and the first 2 days it collects some
dark green junk water in it that I poured down the toilet.

I paniclly changed water 100% last week but today the yellow tint stuff
came back! The live rocks are now covered with some yellow stuff that I
don't know the name.

Is this all normal? This time I didnt do water change but use some
bathtissue to wipe the yellow tint off the . It is better than
last week but I am still worried. Is this normal? The substrate are
covered with brown stuff too.

Thanks!

You rock takes months to cure. You should not have changed your water at
all yet.
Do you have a protein skimmer ? While you're curing rock you should be
running a
protein skimmer 24/7 7 days a week. Smells good I bet : )

I just bought a 25gallon aquarium about a week ago and put the substate
and live rock in it. I haven't put coral and fish in and today I
suddenly found the water turned yellow!

I have pumps (Rio 800) running and using Biological filter calls.. What
do you guys think the problem come from? I changed water (about 60%
change) today but still feel water is yellow. What do you think? Shall
I do a complete water change?

Thanks!
