"Dead" Live Rock

How much of a pain would it be to add dead rock in with live rock ie Live rock which has died out? I mean to setup a tank too, so say 10 KG of live and 10 of dead, plus some live sand.

I know it can be done with the sand, but not sure about doing it with rock???
 
You could use half base rock and half lr and dead sand and the lr would seed every thing. Many people do this to save money in the hobby. Its a great idea imo.
 
FYI - If you are planning on adding "dead" rock that used to be alive in another tank, keep in mind that any nutrient type of problems that existed could still be in/on the rock and leach into your tank.
 
Ok thanks. I think the stuff Im looking at is only dead as its been out of water for a while. What would be the safest way to cure it then?
 
so basically u want to add base rock to live rock if im reading it correctly

does the tank with LR have live stock in it?

if it does that i would not add the "dead" Lr because u will have a cycle

if the tank is empty, u can add the rocks in and let it do its thing

u can do a set up half LR and half base rock, alot of ppl here do it
 
u can cure the dead rocks in the container, ie large garbage bin,

u will need a heater, and powerhead, and if u want a skimmer, but skimmer is not needed i think
 
i would skim and no lights, and would also seed with live rock in that container too. i think that if you are willing to get some die off and have a longer cycle in the main tank, you could do it in there. but understand that you will get a spike and recycle, and some of your live rock may die. also you will want to rinse the dead rock well because all of the little dead bodies that were in the live rock are now just stuck in there and will mess up your water.

i used a heated pressure washer, and mine has been in a trash can for a week with protein skimmer, powerhead, and heater. its about 40lb dead and 10lb live to seed the dead rock.
 
Ok, well I'll be setting up from scratch with some live sand, and some coral sand (1/2 of each) and then use some base rock with live rock, again 1/2 of each. I will hopefully have a skimmer by then too.

If I stick it all in the tank, how long do you think it will take to cure, from scratch? Its 180 litres, so about 47.5 US Gallons. Also I'll have 2 powerheads in there by then too. Looking to set it all up in the next month or two.
 
it depends. not a set time. you just want to run until ammonia, nitrites are 0 and nitrates are 0-20ppm. once ammonia drops to 0 you should start doing small water changes, but none before then. after you stabilize those then add a few fish, NOT BEFORE. this will help give more food for the bacteria to grow. while cycling the ammonia will feed the bacteria and it will be better without fish.

i would say 6 weeks - month before levels drop and fish can go in. 6 months before corals or anemones.
 
Average is 4 to 6 weeks for the cycle to be completed. It can be a tad faster if some of the live rock is fully cured.
Basically it will take as long as needed to establish the beneficial bateria colonies.
Test often, when your water testing reads 0 ammonia, 0 nitrites, and 0 nitrates or as close to ) nitrates as you can get., then your rock will be cured.
 
I figured you were setting up. Throw it all in there, skim it and let it go for 6weeks or until you see amm, trites, then they are at zero and you can detect some trates.
 
Cool, thats fine by me. When will I be looking at clean up crew? Would it also be worth adding a damsel, or molly, after a few weeks to aid the cycle?
 
I would wait until the cycle has completed before adding fishes and/or a clean up crew. Your damsel will probably survive but will suffer form ammonia poisoning anyways, and you will have a fish more prone to diseases. Your snails and onther invertebrates that form your clean up crew will not survive the cycle.

The decaying material from the rock is enough to help the cycle, a raw shrimp will be a better alternative than live critters.
 
i dont think damsels are good anyway. they are territorial and hard as heck to catch. bag that idea. WHEN your tank is ready, get the most timid of the fish on your stocking list. go ahead and post your stocking list and we will help you decide if everything will work and what to stock in what order. also tell us what type of corals, clams, ect you plan to keep.

clean up crew comes with the fish, when everything is stable. i also want to emphasize that water quality is the most important thing, so take it slow and make sure it is right. do water changes often...once tank is established.

i do 5 gal a week on 72, so 20/month which is 28%. Go for around 30%/month. weekly changes is best IMO.

+1

Most damsels are tough little fish and would probably make through the cycle unscathed (which is why some LFS still recommend them). However, in the end you'll still be left with a damsel in your tank :(. NOT a fish that plays well with others!
 
I saw someone metion that you have to wait 6 months after cycle until adding coral, not true. you can easily start adding hardy LPS, softies, zoas and shrooms as soon as nittrate is 0, fish can go in after nitrate is below 40.
