My tank has been running since 18 Feb. Started with 12 lbs LR. Intro'ed some snails and hermit crabs a week later and on 5 Mar added another 8 lbs of LR. All Ammonia and Nitrite tests to date have been 0. Last Saturday I tested for Nitrates...they are sitting at 20 ppm. Did I miss something? The diatom bloom is underway.

Hermits are doing great; hitchhikers such as small crabs, nudibranches,
a micromele undata (http://www.seaslugforum.net/factsheet.cfm?base=micund), tiny feather duster worms, and sponges are all AOK...the LR is teaming with liiiife. Some maco algae (red and green) growing steadily...

Before I add anything...please advise. Did I miss the cycle, should I wait a few more weeks? Want to take this slow and right. Thoughts?

i dont think you missed it. for starters, get a $5 damsel or chromis and toss him in there. If he survives 2+ weeks... your all good. Just dont add too many fish in at one time.
 
first I wouldnt go adding any 5$ damsel just to see if it survives bad Idea Just wait until everything zeros out...Until then stay away from fish and just BE PATIENT
 
+1 on kel2682, dont be cruel. be patient. i waited a month before adding anything to mine too. i started a day before you lol. but you have more live rock. any pics??
 
also +1, patience is the key. keep testing and you will find that it will all level out in time. When it does add live stock slowly and you will enjoy the tank more and less agrivation.
 
It sounds like the major part of the cycle is over or nearly over. As it sounds like this is your first saltwater tank, I'd give it another month without fish. Two months (assuming all parameters were still looking good at the end of that time) was the advice I was given when I first started (this actually came from an LFS), and I think there was a lot of wisdom in that. There's a lot of learning that happens during that first couple of months, and there's a lot to be said about getting familiar with not just the hobby, but that specific tank (they all evolve differently) before adding another variable (i.e. fish). Even when I started my nano tank with fully cured rock and established sand, knowing there probably would not be a cycle, I still let it run for two months before I put a fish in. It's in my office, so of course, my coworkers constantly made fun of my fish tank with no fish. Now, I mostly get oohs and aahs, and that extra month or two I waited really doesn't seem like very long.

And I almost forgot to mention that your nitrates are really not all that high. Start doing water changes if you're not already, and they should start coming down before long. Don't be concerned if you can't get them down to 0 anytime in the near future.

:thumbsup: good post imo
 
Am I missing something? His cycle IS complete.

What is he waiting to go to 0? Nitrates? That's not part of the "cycle" process..that's the end. If he has Nitrates and no Ammonia and Nitrite than it stands to reason his Nitrosomona and Nitrobacter bacteria have always had a big enough population to handle any die off. Not unusual if you have good live rock with limited need to "cure".

If I'm missing something, please point it out.

I would be adding ONE fish and some snails at this point. I would definitely look at the hardiest of fish you want to keep...no "throw aways". A good starter would be a clownfish..they tend to be as hardy as their regular damsel cousins.

Start doing water changes to keep the Nitrates in check. AND STOP ADDING ROCK. If you think you need more live rock, then get it now and wait another week or two to see if you get a spike, but you don't want to keep adding live rock to your system unless you know it is 100% cured and stayed wet in transport.

I'm sorry...I know patience is important in this hobby and everybody loves to post "wait 1 more month"...but what I read sounds like he's ready to rock!
 
i dont think the nitrates are an issue, i dont like the toss a 5$ damsel in and see if it survives thing, and because he never monitored his cycle properly we dont know if he has cycled yet, it may well be he has, id suggest monitoring for another week or 10 days to be 100% sure, then add a fish, not just toss a damsel in, they are living creatures and need to be treated properly, id never add any livestock unless i knew it was 100% safe and under the right conditions, you could be right and he may be ready to go, its just unfortunate a log wasnt kept initially, so id suggest caution, your not missing anything but caution is required imo
 
I'm drawing from personal experience when I say I have setup more than one tank and never saw a hint of ammonia. Once I see nitrate that wasn't there before, I know the bacteria are present and doing their job.

In fact..my current tank that I am setting up now just had a major nitrate spike when I added a whole bunch of live sand from somebody's break down. I expected an amonia spike but never got it..it went straight to nitrate so fast I never saw an ammonia reading. But I guess that's not a surprise when you have over 300lbs of well cured live rock!

Now I will also add that I've cycled tanks way back when..when I didn't have quality LR to start. I certainly understand the process and the need for patience, but I also see on here that many people just like adding their "be patient" $.02 because it's the safest answer. I'll say it when I think it warrants it, but 5 weeks with all 0s but nitrates? ..that's pretty d*mn patient. :)

From what I'm reading..his last rock addition was 3 weeks ago and he has no ammonia at this point. Whatever he may have had is gone.

All this is opinion of course and everybody is enititled to theirs and nobody is ever wrong because opinions can't be wrong. :) ..but I think he's good to go.
 
All...thanks for the posts!

I will not rush it...and I do not use fish as test kits. Still have not decided on what to put in, reading continues...

Michael, "never monitored his cycle properly"... and "just unfortunate a log wasn't kept initially" ??? pretty presumptuous...and incorrect. All ammonia and nitrite tests "to date" have been 0 was in my post. Guess I should have included a day-by-day, by day test result listing, so I did not get a poke in the eye. So's ya know, I tested almost every day (missed 2 days). I was looking for the specific ammonia and nitrite spikes, as I understood would happen. Aw well, with time comes experience

Fizz71, although I feel you are spot on! I can be patient for a few more weeks... matter of fact, we spend hours just looking in the nooks and crevices to discover new things, researching what we find and watching as the creatures already there move about their daily lives.

Thanks again, I will post some more pics (taking some more tonight).

Aloha!
 
sorry i wasnt poking you in the eye? misunderstanding thats all, your first post ask the question did i miss the cycle, i assumed you had asked this question as you didnt monitor the cycle, i felt if you had you would have known the answer, sorry again if i offended you, im not that sort of guy at all, and most folk here would tell you that as well, apologies again

Appreciate that! Sorry I popped off...
 
Hey Defender, I tried to reply last nite, but the site was running poorly for me and something eat it. Anyways,

Sounds like you started with some nice rock. If it was cured when you got it and wasn't dry for long, not seeing a spike is no big deal. One thing I didn't see in your post was mention of adding any ammonia (frozen shrimp or fish food) to the tank. If you did and still have tested zero's this whole time, I'd say get a fish.

If you haven't added a food source, you might throw a dose in there (enough to load the system a bit) and watch what happens. If you still don't see any ammonia or nitrite in 3-4 days, then you know your good.

Just throw another fish in there great answer and Fizz they guy has said that since hes been testing all is zero sounds like he hasnt even spiked... if you dont like the "wait a little longer " .02 cents Tuff
HAHAHA
I figure better to be safe than whining in a few months "How to catch a damsel " I see it almost every week someone new
Either way Good luck hope it works out for you

Let me set something straight...I am dead set AGAINST throwing a fish in to "test" and then try to pull them out later...that wasn't me that said that!!!! I don't think you were saying it was me, but I wanted to be clear. :)

I had said that if he had something hardy on his list of wanted fish, than go for it. I usually add a pair of clowns as my first swimming inhabitants since they are very hardy and if they spike the ammonia for a day or two for the rock to catch up because they are the first fish in...it's no big deal.

Provided you didn't have nitrate at day one and you have it now means the bacteria are present! That is not the same as using damsels to cycle...I do this only when I expect the cycle to be done! BIG difference.

From his last post he said he tested all along and ALWAYS got 0s. That is EXACTLY how I read his post and EXACLTY what happened to my last 4 setups...all re-setups from moves or tank merges as well as my first 75g setup some 15 years ago. A lot of people out there think that they will always have a cycle and need to "wait for it". That's not true of all setups. Starting with good cured live rock can skip the cycle completely. Waiting a few weeks to be sure that's what happened is great...AND HE DID!!!!

FOR FIVE WEEKS!!!! :)

If he said it was only a few days since the rock went in I'd be the first one in to say WAIT.

Please don't read this as I'm trying to argue with anybody...I'm not. I've been on this site a while and in the hobby even longer and as much as "wait" is a generally a good response, some people tend to throw that word out blindly because it's an easy, safe response and MOST people who come hear start asking questions BEFORE waiting which is why it's generally an accurate response. :)

But I felt I recognized in this case that we actually have one of the few "patient" new hobbyists out there that waited before they even posted!! I also read into the post that he was looking for a cycle probably because everybody told him he needs to have one. (not the first time I've heard that) That's how I read the first post, and that's how I gauged my responses.

I posted to make sure he got the idea that not all tanks "cycle" over the course of weeks or months and that some tanks are cycled in just a day because of good cured rock!

I wouldn't go throwing some $300 "difficult" fish in there, but if you have a cheap hardy fish on your wish list (like a damsel or clownfish) I'd go for it. You can wait too...there's nothing really wrong with that either, but if you're itching..well...scratch it :)

I personally don't like it when a cycled tank sits idle--the bacteria need to work (eat) or they'll die. That's also why you are told to add fish slowly..the bacteria levels will only stay at around your tank's need...no need? They die. So first ad snails/crabs so you can feed the tank too, then wait atleast a day or so and add some hardy fish. Let the bacteria catch up, then start adding the other stuff since the bacteria have a good head start now!

It's somewhat simple chemistry that you don't need to know if you just follow the "rules" of waiting/cycling/etc....but if you understand the chemistry first, IMO you know better what to do.

I am certainly no chemist, but I've spent years trying to understand as much of the chemistry side of this hobby as I can.

I've also seen people on here that tend to post "wait" without thought which is what I talking about earlier. It IS a safe answer, and NEVER wrong, but also not always the only "right" answer. :)

Good Luck!!
 
Hmmm kel, did I post bad advice? How so? Did you read my reply or just scan for key phrases to flame? Since you're either slow or missing the point, I'll break it down for you.

Since he started with some nice rock, IF he has been adding a food source these weeks and still tests zeros with the exception of nitrate climbing to 20ppm, then the nitrafication cycle is done and waiting another week/month/year won't make it anymore done. He's ready for a fish.

IF he has not added a food source these weeks, and since
(judging from his test results and all the infauna present) he had very little die-off from transport, he should add a load to his system (in the form of fish food or frozen shrimp) and watch his test results for a few days looking for an ammonia or nitrite spike to ensure that he has enough nitrobactor and nitrosoma bacteria to handle the load a fish would place on the system. Once again blindly waiting without testing the system does him no good.

Perhaps if you spent more time reading here to further your understanding of the hooby instead of just looking for someone to throw a rock at, you'd know this already. Just my .02

Defender, sorry to rant on your thread. I set up a 34 gal over christmas for my mother with LR that I cooked for 4-5 weeks. That rock spent about 36 hours in a cooler (waiting for christmas morning) prior to setting up her tank. Day 2 and 3 testing showed an ammonia reading of 0.25ppm and nothing there after. No nitrite at all. If you start with a healthy bacterial population, it's normal. If you haven't been feeding you system at all, throw a couple cubes of mysis in and watch for a spike for a few days to be safe. Best of luck.
