New Tank - Old Tank

Recommended Posts

Hi all,

I am new to this forum. I have had fish most my life but been away for about 7 years. Now getting back into the hobby, except now nano style. I have a new biocube 14. I put 20 lbs live sand, 15 pounds of cured live rock from store aquarium, and real sea water. The tank has been going fine for the past 5 days, no spikes in anything (NH4,..etc). (I have a couple fish and small cleaning crew in it also). My question is.... since I used so much "old stuff" to make the tank, is it safe to start adding corals now? Or should I wait? I am planning on 2.5 gallon sea-water water changes once a week and already did my first today. Any feedback is appreciated. I am excited to be getting back into the hobby.

What is your phosphates? I know that could be part of the 'etc', but still.

 

And have you tested your filtration system?

 

Cure live rock and live sand should make it a pretty much instantaneous cycle, but always better to test your filtration capability before adding anything.

You need to cycle your tank before adding any livestock. Was the live rock/sand from an established tank? Did you test the sea water before adding to your tank? It generally takes a month for a tank to cycle, but if you used pre-establisehd live/cured rock from an existing tank, your cycle could be days (or even a day/no cycle at all).

 

If your fish are fine now, you probably dodged a bullet. Def. keep tabs on them over the next few weeks. Test your water regularly as well in the meantime.

So no phosphates?

 

Just wondering, why are you so concerned with phosphates? It sounds like the OP is more interested in a regular mixed reef than in a low nutrient system... Low levels of phosphates IMO are acceptable. If the OP does test and get high results then that may be an indication that the rock wasn't cured for long enough but really all he can do at that point is move on.

 

Agree that as long as your rock was properly cured there should be no spikes and as long as you're not overloading the biofilter there probably never will be. Not a bad thing since you already have livestock. I'm usually leery of stores that claim to sell fully cured LR... So I usually give it a litte time and/or test the water, but you're kind of past that now so it doesn't really matter.

Because it is needed to know how to move on. Oh I don't give a damn about low nutrient systems, but I do worry if it is wayyy too high, in which case he has to do something about it first.

 

Phosphates are definitely important for coral growth, but high levels can have a direct impact.

 

So yeah, just want to know is all.
