Looking for LR

these are Serpulids. Tiny harmless filter feeders that are common in almost every system that's set up with good quality liverock. These are not a bad thing. They multiple quickly but dense populations always end up "burning out" and going away.

They've grown into a colony in my hang on Remora skimmer. i think they're pretty cool myself
 
There seems to be some misunderstanding here. I think you've all got the impression that I'm a beginner at this. Nothing could be further from the the truth. I had a reef tank years ago up and running for about 3 yrs. We had a bad storm that knocked out our power for 4+ days and that was the end of that. I currently have a 125 gal thats been going for about 2 1/2 yrs.
Now why I never heard of these methods of "cooking" or the bleaching/ muratic acid baths for rock is beyond me. I certainly have spent enough time reading forums and talking to people.
It does explain a lot of the problems i had when I first set my tanks up tho. The algae outbreaks that I fought for the better part of the first year. Thanks for all the great advice. I'm formulating a new plan here.
 
I think we ALL have a lot to learn.

I would hope somebody setting up a 300 wasn't new to this!
Free thread bumps and info... You can't go wrong.
It's already helped you rethink things :)
 
"cooking" liverock

"cooking" liverock

(as described in the link I provided earlier in this thread)

Although it has some similarities to curing new rock I would not say the two are exact. Curing has more to do with ammonia/nitrate/nitrite cycle as well as dead dying life that came in with the rock.

"Cooking" is a method of PO4 reduction.
 
Ok so cooking it is. I think I'm just gonna get the new tank up and running. Then move my fish over to it and shut down the other tank and cook all the rock in it. Its starting to look kinda crappy anyways and could use a revamp. lol
I have 2 more questions.
1. I've got 5 - 6 pieces of dry rock I bought at my LFS.they are bleach white and there is no signs of anything at all on them.They've been soaking in room tempeture(about 69F) RO/DI freshwater for a about 2 weeks now. Do you thinks its safe to just go ahead and leave them in the new tank when I add salt?
2. Do I need to put a heater in the tub(s) that the rock is cooking in?

I've got about 90# of dry GARF agrocrete and former live rock that has been sitting for a while in the basement if you're still looking. My tanks were never too heavily loaded, but I'd do the cook/clean cycle just to polish it up as others have recommended.
$50 and it's all yours. I'm up by Seabreeze in Rochester.
