Pristine water, keep or throw out?

+1 Bogie, water should be fine to use.

 

I really don't no how to respond to this but I'll give it a shot.

Nitrates are the very end product of the de-nitrification process so if they are present in low ppm's that's a good sign , And since there is no load adding more waste products to deal with I'd dare say his NO3's are as low if not lower then the average aquarium.

As for depleted 0'2 that's just slight at best and again since its going into a new system it will exchange any dissolved gases just as fat and even sooner then a average tank will . 0'2 is always being depleted and I'd feel better using it in a new tank with nothing rather then a established system with corals and fish.

As for any elements being depleted noting in there to deplete then at the worse the cycle cause any acides then the calcium based rocks did their duty and took care of it

And true the bacteria that convert ammonia and nitrites are aerobic and that fact that he has any nitrates tells me there would be plenty of oxygen as that’s the more oxygen dependent bacteria hence the rumor of wet dries being a NO3 factory

I myself have used this type water several hundred times in the past and never ever had any issues But I only used it if all the parameters where correct aged water would be and is always preferred to new water anytime .

 

Turns out the one test I do not have a kit for is Nitrate. How did I miss that one? Guess I will hop in the woodie, spend $12 in gas (reg. is $4.85/gal here and Oprah has said nothing) and pick up a test kit at Petco. As for using up all of the elements I think the RO had already taken care of most of that, at least that is what is claimed.

 

Well if you do not have any ammoina and or Nitrites then you have some nitrates and if ther are low thats a plus But I'd still use the water . If not they will be no more then anyone elses systems with animals in it.
What do you use to pull that old woody down the road ? A small Block Ford or Chevy ? I'm more of a gear head then anything else Thats my true love

 

Why would u throw it out? When u cure live rock and cycle a tank its usually in the aquarium your are cycling and u dont drain yer tank and refill with new water when its done cycling. I bet u are lucky to have 25 gallons if that in that can with all that rock. Ive done a few tank transfers and i always use the old water in the tank im emptying with great results.

 

Just to chime in. Lots of good things have been said. From what I know, I'd say a lot of it is right on. If ammo and nitrites are 0, then there should be some nitrates present. That would be enough for me just to make new water since it's not that pricey and you already have an RO/DI at your disposal.

There is no such thing as cycled water. That's true too. We can tell where we are chronologically in the cycle from the condition of the water--not the other way around. If such a thing a cycled water existed, we could take water from a cycled tank, and transplant it into a brand-new tank and be ready for corals the next day. Alas, not the case.

As for the "depleted O2" comment, remember that a marine tank is always in flux, and if your system is just right, you could add "depleted O2 water," and it would be saturated with O2 within a few hours.

In my opinion, I'd just use new water; although using the water of which you speak probably isn't such a bad thing.

 

Personally I think the elements in the water has already been used by the other life that's on the lr.

 

I'm not sure what 'elements' you are talking about and what life would be using these elements.
Typically the elements in fresh mixed saltwater that we are most concerned about are used by corals in our tanks. plain LR will not remove any elements as there is nothing on it to consume these elements.

What is happening is the die off of bacteria and other living matter is being converted from ammonia to Nitrite and then to Nitrate. the Nitrate is then converted to nitrogen gas and off gases out of the water.

Nothing else is really going on that we are concerned about.

The water should be fine

LMAO, over water. Its ok. No one can say for sure if he should use the water that it will or won't cause problems. ITs going to have a ton a crap in it. We all want to help and can take our experiences and tell what we think. If I was using a seperate tank to cure lr in it, I would not use that water. The lr is the good stuff. When I transfered my tank in one night of course I used the old water. But he has a new tank. The 25+ gals of water its going to make that big of a difference? Only if it has bad things in it.

 

Thanks everyone,

I did not mean to get things too controversial but nothing but good comes from discussions about a subject that has different view points. To add some more info to the equation the nitrates turn out to be between 5 and 10 ppm. I think this is well within desired parameters.

I am going to take the next few days (tank does not arrive until Monday) and reread all of your comments. I will start with just new water to situate the LR and then probably use the water with known character to top off the tank. I agree, there is not much of it as the rock in the can is placed like a jigsaw puzzle. I did make sure the favorites are at the top so I have them to work with first. I think I have too much LR if there is such a thing.

The street rod has a 350 chevy and 350 tranny. I used to built engines for Traco engineering who built them for Penske and Donahue's Cam Am cars. My training is in small blocks but I also dabble in Porsche engines. Did all the work, wood, body and drive train myself, more fun that way and a lot cheaper.
