Dry to live rock

[Sir_Andros]

So i started my tank a little over a month ago and have dry rock in my dt and premium live rock in my fuge. My live rock has turned from white to bright green is this the rock becoming live or something bad

I check my parameters every other day and always perfect.

Its the normal green algae stage that you get with a new tank. Its a good thing

 

[Sir_Andros]

Crabs love it thats for sure lol

 

[Pete polyp]

As long as it doesn't look like fur you're good.

 

[Sir_Andros]

Ok nope no fur dumb question but it was furry lol whats that mean

Green hair algae

Turning green means your phosphates are a bit high, you should be seeing pink and purple growth instead.

Every tank I have set up has a green algae stage around the 1-2 month mark. I always thought it was typical of a tank that age

 

[Reefing Madness]

I've only run into the green stage with to high of phosphates. Diatoms happen, algae does grow, but usually its HA or smalll spots here and there, but just green algae growing on the rocks?

 

[Pete polyp]

Yeah, they turn bright green, almost neon with every setup I have had. Not hair algae or anything, but green film algae.

 

[Reefing Madness]

Right on.

 

[Sir_Andros]

Well my phosphates are 0 and my fuge has red and pink all over it just the dt rock

 

[Sir_Andros]

Every parameter is perfect to the t

 

[Reefing Madness]

What are you measuring the phsophates with?
(some dry rock tends to leach phosphates pretty good.)

 

[Sir_Andros]

With an API reef master kit

 

[Sir_Andros]

Fyi the rock also has red and pink in small patches

Then you more than likely have phosphates. The API can't test out low enough.

Its not algae its cyanobacteria.. If it almost a florescent green.. When using dead rock this is a normal stage and nothing to wory about.. It eventually will die off...

Usually diatoms and then florescent green cyano.. Next stage will either be red cyano or green algae..
