live rock turning....brown?

its quite possible that the bulb change has caused the diatom out break...i would not say its that much to worry about..It realy does not take much for a diatom bloom to occur....Another reason could be high nitrates and phosphates...What are the current water params for these out of interest mate?

ph 8.4
ammo 0
nitrites 0
nitrates 20 ppm


im not sure what the gph on my one powerhead is, it came with my old 55 gal tank. its pretty extreme, and i even have it turned down to almost half or itd blow stuff straight out of the tank d-:
the other powerhead is a koralia 1
and the tank is a 29 gal

hope all this helps

sounds like its not too much to worry about, but just want to make sure that my live rock will regain its color and that its not going to affect anything in my tank.

as for stock, i have 2 Ocellaris clowns, 1 gold head sleeper goby, 1 cleaner shrimp, a dozen blue legged hermits, 10 astrea snails
1 green open brain coral, and 1 BTA
 
what's your calcium reading man? Coralines don't do well if there isn't enough available calcium in the water for them to use for growth. How old is your tank if it's fairly new I'd assume that you have more than an average amount of free silica in your bottom as aquarium gravel is pretty much dyed glass. If you plan to reef I'd get rid of it and replace it with sugar grained sand otherwise you'll have huge nitrate issues.'

it actually IS fine marine sand, mixed with fine live sand....
 
It does look blue in that last photo. Is it just an odd angle catching a reflection?

so that previous post was referring to the fact that it's colored? I thought he meant there was a distinction between GRAVEL vs. SAND. It is blue marine SAND, mixed with live sand. I didn't know it being colored would make a difference though :\
 
i think before we start getting gittery about the type of sand, lets see what it is first?..

Did you buy the sand yourself? If so, do you remember the maker of the sand? or where you brought it from so we can look to see if this type of sand is a potential problem..
