some of you who helped me out yesterday knew i was having trouble with measuring my salt levels and my hydrometer, and it put off my purchase of LR. Not only was i disappointed that i had to wait to buy it, i was also disappointed when i looked at it in the store...the 7.99/lb stuff was tiny little rocks, and the 12.99/lb was big, but just ok looking, nothing to make me say wow (except for the price!).

so i came home, upped my salt in the tank, and browsed here. i was looking in the for sale section and saw that a member was selling his LR for 2.50/lb! the pics of his tank looked beautiful, and the feedback from the sale of his corals was excellent. i PMed him, and sure enough, he had plenty left, and he lives about 20 minutes from me. so this morning i went back to the lfs with my broken hydrometer and a cup of water. it was up from yesterday, but still low, and the hydrometer was off by 8 points. they gave me a different one, (different brand, more expensive, but exchanged it for the same price), tested my water on it, and it was much more accurate...still off by -1, but better than -8! so i came home, mixed up some more salt, tested it, back to the lfs to confirm, all looked good at 1.023, so i called eugene, who was selling the rock and went to meet him. he wound up giving me 25 pounds of figi rock from his two year old 75 gallon tank for $50! it looks really nice.

so, as disappointed as i was yesterday, it turned out to be a great experience for me. still getting a refractometer though.

what can i expect now from a cycle with rock that's been in an established tank? it was in a styrofoam cooler wrapped in wet newspaper out of the tank for about 30 minutes. will that cause a lot of die off? here are a bunch of pics...lmk what you all think, and any ID info would be appreciated as well.

I wouldnt worry about die off because your rock doesnt have much on it. The pieces of coral that are on it are montis. Cant tell the color but probably brown/purple monti. I would scrub the rocks because it looks like they have a lot of algae on them. Especially the first piece.

As far as cycling, yes, your tank will cycle a bit quicker because of the added bacteria but nothing dramatic. If you are setting up a new tank I suggest you take your time and do things right!

Good Luck.

die off doesn't necesarily mean corals only. you can have die off from all the beneficial bacteria and any other life on those rocks, like pods or mini stars,bristleworms,coralline,etc...

i would not scrub the rocks. i don't see any macro algae on there that would cause concern.

What do you think all of that dark green stuff is? That is algal matter that will start to break down in the tank. It is not macro algae. Its better to just brush it off than introduce it into the tank. That will only release small particals that can seed more algae growth.

When someone talks about live rock I think of new rock that needs to be cycled. He did not indicate whether it was new or not so I erred on the safe side. Regardless, I recommend a good cleaning.

Click the 1st and 8th pics. You can see that the algae has overpowered the coraline. I dont know about you but I would not put rock like that in my tank. Especially if I was just starting a new tank. I only speak from my experience because it happened to me.

Its better to be safe and start a tank on the right foot than to do it the wrong way. To be honest with you, I would put the rock in a container anyway and cure it. This way I would know that I did not introduce any major problems into my tank.
