Opinions on how to start cycling a tank

[Dork Fish]

**For the below, we are assuming no established tank to pull bacteria from**

I have been looking online, and have seen 2 main schools of thought on cycling a new tank:

1) Cycle from day one with plants in the tank, and low light.

2) Start the cycle with absolutely nothing living in the, and also no light until ammonia and nitrites are zero (usually 1-2 weeks). Then and a couple plants, use low light, and add a few fish once every 1-2 weeks depending on ammonia and nitrite levels.

 

The second option seems to be the safer option and allows the bacteria to grow gradually with the load in the tank. Thoughts?

If I was looking to speed things up a bit I'd use (and have used) Fritzyme 7.

I have never not at least put plants in from the start, and have never went without light.

With or without fish you will need to feed the tank.

Assuming you have no other tanks in the house this is the process I would use.

Setup the entire aquarium including plants. It is a pain in the ass to go back later and add plants into the aquarium.

Get one or two sacrifice fish (guppies for example) 

Also get the liquid bacteria treatment.

Now fill the tank with chlorine-free water, add the liquid bacteria based on total volume of the tank, and add the fish.

Every day you need to test the tank and do water changes as necessary. Those fish may be sacrificial but that doesn't mean they need to die the first week.

With each water change add a bit more of the liquid bacteria based on the amount of water changed.

You should have a peaceful couple of weeks. But the tank STILL WILL NOT BE READY FOR THE NORMAL FISH LOAD. When you add the fish you want you will get a bacteria bloom. Just live through that and keep an eye on the parameters.

 Would just add water, let it sit a day, then add fish (a modest amount, you want to gradually increase population of the tank over a period of time) and dose with Fritzyme 7. 

I don't think it needs to be over complicated.  As long as you're initially dosing with a good bacterial starter according to instructions (and not overstocking on day-one), you should be fine.

[Dork Fish]

I did use a bottle of the Fritzyme 7. 🙂

I suppose I will pick up a few plants and maybe 4-6 nano fish.

How would you disinfect the plants, if you only have the one tank?

You can do a bleach dip -- Bleach Dip Instructions

If done this numerous times to great effect. I typically do this to combat black beard algae on anubias.

@tolstoy21 Yeah I saw the bleach dip. Also saw a peroxide dip followed by a saltwater dip. I was opting for the later since it seems a bit safer for the plants. The peroxide kills off algae and most parasites, while the salt kills of the rest of the parasites and snail eggs.
 

 

[tolstoy21]

The bleach dip is not so harsh, but both work. 

[Dork Fish]

@tolstoy21 which would be safer for Amazon Swords, bleach or salt?

[Ken Burke]

I’m curious, what are you disinfecting from the plants?  Plants are covered with the beneficial bacteria you are looking for. I normally just plop then in the tank, but I suppose I could leave them overnight in a seltzer bath if I worried about algae or snails. 

[Dork Fish]

@Ken Burke Concerned mostly about snails and algae. Deciding on a salt dip or a bleach dip.

[Ken Burke]

I wouldn’t do either, but would do the reverse respiration @Guppysnailis always talking about.  Much more plant friendly

Here is the post

@Ken Burke @Guppysnail Wow this is great, I had never heard of this. Will give it a try.

[Dork Fish]

@Ken Burke @Guppysnail Scratch that, the walmart near me doesn't have seltzer water, and doesn't know when they are getting it in.

Do you think that the plants would be fine in the 5 gallon bucket over night until I can try another store tomorrow?

[Ken Burke]

Yes

[Dork Fish]

@Ken Burke Looks like the seltzer water is going to be about as much as my plants cost, I am going to try the bleach and if that doesn't work, then I'll just buy more plants 🙂

I can see the reverse respiration being good for more expensive plants, or high quantity of plants though.

[Guppysnail]

@Dork Fish look for club soda. Both club soda and seltzer should be about $1 a bottle. If you look through te article bleach causes a lot of damage to plants. 

[Dork Fish]

@Guppysnail Ah okay, I saw club soda and read it had extra minerals in it that seltzer didn't have. Didn't know if the extra minerals would be bad or not.

We did not test it but other folks have substituted it with success. 

[Dork Fish]

@Guppysnail good to know :)

Hi @Dork Fish,

As @Ken Burke said, 

RR uses asphyxiation vs toxification to eliminate pests. They are eliminated due to a total lack of oxygen vs using poisons. As such, it leaves no residue but water once complete. It also has so far, enjoyed 100% pest elimination and about 98% as an algicide all the while, not damaging the plants. In part this is due to the high pressure in seltzer as RR is the only method, we’ve seen that reliably eliminates MTS due to this pressure penetrating the operculum. You’ll also notice plants become more rigid and greener as the CO2 charges the chloroplasts although we’ve yet to associate this to any growth stimulation.

The primary advantage in using RR vs more toxic and caustic methods is its efficacy and the lack of plant damage. Take a look at the microscope images comparing the chloroplasts of an anubias treated with 6 different methods. Notice the cellular damage that occurs in all but RR.

If you navigate to that area of the website, Reverse Respiration, there are video links as well. In them you’ll see chloroplast motion literally stops in all but RR and of course, untreated plants. Many people have reported a short-term growth acceleration as well. We did document one such growth spurt on a hornwort treated with RR which grew some 80% faster for about 3 weeks before normalizing.

We haven’t seen any discernable difference in performance between seltzer and club soda, most likely because the mineral content of club soda is so small.

Many people here use a SodaStream device as it’s substantially less expensive by volume than bottled. I have repeatedly purchased seltzer with delivery on Amazon where the price varies but averages at about 0.90/quart:

Amazon.com: Amazon Brand - Happy Belly Seltzer Water, 33.8 Fl Oz (1L) : Grocery & Gourmet Food, Good luck.

@dasaltemelosguy That is great, thank you for the info 🙂

[Dork Fish]

@nabokovfan87 @Pepere @mountaintoppufferkeeper So I have had the 4 scissortail rasboras in the tank for about 5 days now. I have been feeding every day, to encourage ammonia for the bacteria to grow. 

I tested ammonia and nitrites today, and they are both at 0.

Should I add a couple more rasboras and maybe a bottom feeder?

Bioload just seems like it might not be challenging the bacteria currently.

Nope. I would just let it do its thing.

How many rasbora in total do you have to add to the tank?

You might end up seeing 0-0 and then seeing nitrates.

Not seeing ammonia or nitrite isn't a good or bad thing. It's just a sign of water being safe for the fish. Seeing the nitrate means you know it's processing the ammonia from the fish.
