Cyanobacteria - New Tank

Member
My tank is 4 days old:
75G
75lbs Fiji Cured LR
80lbs CaribSea LS
Mechanical Filtration - Eheim Pro II
2 x 900 MaxiJets
2 x 1200 MaxiJets
Ramora Protein Skimmer (1x1200 MaxiJet)
Outer Orbit 10,000K PowerPaq Metal Halide
Question: Since my tank is still cycling, is there anything I should be doing or should I just let this stuff grow and dissipate (hopefully) after the cycling completes?

No, you are fine. Its called the new tank syndrom for a reason. better to get it over with now.
What are you using to kick off your cycle if you don't mind me asking. Barry

I have a lot of LR & LS, should I be using something else? I was told that these two can be used to cycle and that I wouldn't have to introduce anything else.
Is this correct?

depends on how your water treading are. Sometimes throwing a dead shrimp make it have a "harder cycle" and the bigger swing in nitrates you get in your cycle makes for a more durable tank as you will get more beneficial bacteria growing. The harder the cycle is the better off youll be in the long run...

Was your rock pre-cured? Have you taken an ammonia reading? If your rock was already fully cured and you are not getting an ammonia reading then you will need to start the cycle. Add a raw coctail shrimp to your tank and monitor ammonia. When it reaches 1ppm or close to it, pull the shrimp out and let the cycle complete.

Good point, my rock was cured, yes. I didn't really monitor closely the first few days and I was told by the LFS that it could cycle in a couple days with the amount of rock I have and it's quality.
My story is quite interesting, posted a few days ago, but in short, I was given the OKAY to use 50% of my freshwater (ran FW tank for a year) and the remaining tapwater to start my SW tank. Don't ask me why someone would okay this but I guess that day I spoke to a new employee at the LFS. Anywho, I did have some bacteria and buildup in the tank and I'm sure this triggered an instant cycle with all that leftover junk in there. Fortunately, I never medicated the water and it was nice and clean, so I opted to wait it's course and it is looking okay at this point.
Ammonia is 0. Nitrite is 0. Nitrate is now at 10ppm with a considerable algal bloom ocurring but this appears to be normal while my tank begins. Comments?

I did read that post and told you I didn't think it was a good idea to use the old freshwater. Anyway, I am glad your readings are good. I personally would spot feed the system just to be sure. Take a small amount of fish food, drop it in and let it rot for a few days. If your ammonia spikes a little and then comes back down then you are good to go, if it keeps rising then you are not cycled and have to wait for it to come down and then the nitrites to climb and come back down. If you don't get at least a small spike then you didn't add enough food. The ammonia in an established system will spike and come right back down. This is the best test to be sure your system is ready for life.

I agree with you not thinking it was a good idea, problem was by the time I posted it was too late -- otherwise I would have told that crack smoker at the LFS to have a nice day.
I will take your suggestion and add a pinch of food. However, please correct me if I'm wrong, but can Nitrates exist without Ammonia?
I have less than perfect nitrate reading and therefore would have to assume that ammonia did exist. Unless I'm confused about the cycle -- which is completely possible.

Which means what? Start over or just kick start another ammonia cycle and rid the nitrates through water changes after the cycle completes?

Yes, you still have to spot feed your tank to be sure that it is cycled. Your diatom bloom (that you will have shortly) will feed off of the nitrates if you leave those in there. It is an ugly disgusting brown mess that covers everything. It will eat all of your nitrates, but it will also take longer to go away if the nitrates are there because it will have a tasty food source.

sepulatian -- thanks for your help. It is much appreciated and I still need it. :)
I have added a pinch of food, how long will it take to spike the ammonia? Hours/Days?
Secondly, when I said in my previous post "Start Over" I was inferring removing all the water, and starting again. Do you think this is necessary -OR- can would I be okay by just adding the food and letting something kickstart? (which is what I've already started to do)
Thanks!
