Alec's 75g cycling thread!

[awilson133]

Hi everyone! I got a new but used 75g tank and I need some guidance on fishless cycling it! I know how to do it I've done it before. I just need some guidance
Ph 7.5
Ammonia 2.0
Nitrites 0
Nitrates 5.0
I'm using a established fluval 406 canister filter. I dosed the ammonia to 4.0ppm last night around 6 so ill check again to night help appreciated

Let us know how the test comes out.

By 'established' did you mean that the filter media came from another tank? If so, that should speed cycling significantly.

 

[awilson133]

Yeah the whole canister came from a cycled 55.

Sounds good so far. The cycled filter should help immensely. Keep us posted. What are your plans for the tank? It's a great size!

Congrats on the 75g!! Looks great so far- this should be an easy cycle!

 

[awilson133]

Thanks I havent really decided yet. Ciclids are a no go:/ I'm checking my levels now. I did however do a 50% wc cause I needed to move the tank like 2 more inches. So my ammo might be lower than it should because of the water change. Levels as of now are..at..
Ammonia 2.0
Ph 7.9
Nitrites 0

 

[awilson133]

My levels as of now are.
Ammonia 2.0
Nitrites 0
Ph.8.0
Should I wait another day? Or bring it back up to 4.0

 

[jlk]

Give it another day before dosing. Check your nitrates, too. With the cycled media, I expect to see some already. Looks great!

 

[awilson133]

Okay sounds good I put some fine flakes in there before I left the house ..

 

[awilson133]

Okay I checked today and my
Ammonia 0.25
Nitrites .50
Nitrates 30
Ph 8.0

 

[awilson133]

Should I start adding some more?

 

[awilson133]

I dose to 4 ppm...

 

[awilson133]

Soooo...my
Ammonia is 1.0ppm
Nitrites 0.25 ppm
Nitrates 50 ppm
Ph 8.0

 

[jlk]

It sounds like your tank is doing well!

 

[awilson133]

I brought it back up to 4.0ppm is that okay?

 

[jlk]

Yep!

 

[awilson133]

I add a old established media today.
My ammonia .50
Nitrites 5.0
Nitrates 90
Ph 7.9
I think its moving along quite nicely

 

[awilson133]

Ammonia .50
Nitrites 5.0
Nitrates 160
Ph 7.6

 

[awilson133]

Should I do a water change to raise my Ph and lower my nitrates?

 

[jlk]

Let's wait one more day to see where your ph goes. The nitrate level is not a big concern but with your nitrites 5(+), it won't hurt to bring them down some. If your ph drops any further, it's definitely time for a big wc.
