View Full Version : High nitrites in new aquarium

06/16/2012, 05:11 PM
Ive got a large aquarium with with no fish and high nitite levels.

10lbs live sand
120lbs dry live Pukani
10lbs of live rock/rubble.

was told to use "NITE-OUT II" and "MICROBE-LIFT" so I used it as instructed

Tested water today, its been set-up for about a week, and found high levels of nitrites and nothing else.

Not going to do water change because its 200 gallons.

What can I do and what caused it?

Also all dry rock was clean when i put it in.

You are going through the cycle. There was initial dyoff that formed ammonia, which is converted to nitrites, which is what you have. Eventually it will form nitrates. I would do a bit of reading about the nitrogen cycle and cycling a tank. It will help you down the road- check out the stickies!

your tank is just cycling brotha. was the rock cured before you put it in the tank??? that can make a big difference. Also do be scared to do water changes. since you have no livestock its not a biggie, but in the future you would want to do a 30% change or so, depending on how high it is. Ammonia, nitrite are really harmful to fish and coral will die. good luck

ok, the live rock was cured and the live sand is natures ocean or something like that.

what is your nitrite level?

06/16/2012, 08:42 PM
5.0 ppm

You are going to have big phosphate problems with that pukani assuming you didn't take the proper procedures before adding it. Also not doing water changes might not be wise for a begginer.

I didn't know BRS sold cured pukani

If it was dry you have to let it cycle to become live

I did not get it from BRS, i got it from a local shop called Crystal Sea Technologies.

It was pressure washed before I put it in the water and also sat out in the sun to dry.

IT appears that the cycle has started to come along a little more, today the water is much clearer than yesterday.

In a few days I will re-test it.

Ok, well if it was dried when ou bought it, it still isn't live rock but will quickly become live from the seeded live rock you used.

I have 120 pounds of pukani rock that I bought dry and it took around 2 months for my full cycle in a system with 183 gallons of total water

i know have green/brown algae growing in large areas on my glass, should i leave it or clean it?

on the good side, i have spots of coraline algae on all my rock!
