maybe u can tell us your water parameter ?

if urs is a new tank then most likely suffering from diatoms(brown algae), i experience b4 "new tank syndrome" most likely due to high phosphate levels. if indeed the problem is diatoms then cleaning crew such as turbo snail will help...

what water are u using for your water change ? sea water ? if mixing salt then are you using ro/di ? or tap water ?

water parameters like po4 and nitrate would help ...

help us to help you, pics wont hurt either !!

yep, i feel its brown algae / diatoms as well.

Conduct water change.

In the mean time, get turbo snails. they'll clean up the rocks efficiently!

i guess you mix your own from tap water? can be the reason why you get cynao bloom.....as our water contains silicates, phosphates, adds to your water quality woes....do you over feed your live stocks?

Thanks for all your advise. Don't have digital Camera. But will try if i can find one. But i guess, is the water i change also. I use tap water to mix the salt but i use a pump to pump it for a few days at least. Does it help? Will try to change the water more often and see if it help.. Thanks for all your advises. Cheers...

No use. Leaving water overnight does not affect Po4 or Silicate ....

(Not confirm, any chemist can help )

If that is the case , where can i get RO/DI water to mix? Any idea?
