Cycled already?

Too many tanks are almost enough...

Hey there!

Been lurking in the back of the tank for the last month, thought it was time I came out from behind the plants and ask a question.

My 10 gallon finally finished cycling, so I got me a 29 gallon (the 10 was WAY overstocked-can't resist buying fish when I go to PetSmart; salesgirl there is worse than a Crack-Pusher

:D )

Anyway, got the tank kit home last Friday night, set it up with heater, filter, gravel and water. Saturday went to PetSmart and bought a LOT of plants (3 tall sword type, 3 Java Ferns, 2 Val Italiano), 2 driftwood type things and other bit's and bobs (another airpump, bubble wand, ammonia stick-on thingy).

Took 6 coffee cups (rinsed the cup out first; is Kona Coffee bad for fish?

:D ) of gravel from the old tank and sprinkled it in the new tank and squeezed the sponge from old filter into tank. Planted all the new plants and transplanted the cobomba from the 10 gallon (was a bit crowded). Tested tank (using the AP Master kit) and all read zero.

Sunday, bought 5 Zebra danios to start cycleing new tank. Decided to move the black molly and the 4 glass fish to new tank to ease the bioload on the 10 gallon.. Tested again, all still read zero.

Monday, passing by the Evil PetSmart; 4 dark veil tetra somehow came home. Tested again-still nada, zip, zero, yet!

Yesterday, the ammonia thingie went to green (alert), tests still zero.

This evening, tested; zero ammonia, nitrite and nitrate, PH of 7.3. Temp is 78.

Anyway-to the question (bet you thought I'd ever get there!). Could my new tank be cycled already from the gravel (which I forgot to vacumn before moving), filter squeezing and transplanted plants? I lost a bunch of neons and 3 mollys in old tank before I read here about stocking and cycling; ammonia and the nitraites spiked something fierce 2 days into the old tank, so I'm running a bit concerned!

Eddited to add that all the fish all doing great, busy swimming around happlily ad all the plants are growing-the Vals have grown 2 inches in the last 3 days!

I don't know if your tank is cycled, you'd have to keep testing. I'd be concerned with the amount of fish you've added all at once. Even into an established tank it seems like a lot. ultimately to arrive at the number would be fine, but I think to much all at once is going to stress things.

Perhaps because it is a large tank, it is taking longer to have traceable amounts of ammonia and stuff. I'd test it a lot to make sure your fishies stay safe.

Yes the gravel helped, yes the filter squeezing helped and YES the plants helped. The plants were the biggest help, IMO, as they naturally tank in ammonia to grow. The filter squezing was the second more important thing, for that innoculated the new filter and as there is any leftover ammonia or nitrite those bacteria will be there to do their thing. You see, plants do tackle the ammonia but they don't touch nitrite, the filter has to catch any of that. So, do measure nitrite, and do water changes if it gets out of hand, it may go up even if the ammonia never does.
 
If your readings are still 0 I would be a bit leary, even with the plants, 14 fish is alot to add in a couple of days and have nothing... I might have my water double checked at the LFS. I'm not sure why your ammonia alert thing would have went to alert, and they test kit still said 0???
 
Thats what has me baffled; the tests all come out zero (ammonia is a bright yellow, nitrite sky blue and nitrate also bright yellow-as of 2 hours ago-testing everynight)

The Seachem Ammonia test thingie has been o green for last couple days.

Just did a sniff check-no smells (had a bad smell from my 10 gallon in mid cycle).

Guess I'll keep and eye out and hope for the best!
 
I'm not shocked that you're not showing ammonia or nitrites but I wouldn't go throwing any parties yet either ;)

The bacteria colony as a whole in you existing ten gallon could only grow as large as the supply of food allowed. So, if you had 6 fish in the ten, the total community of nitrifying bacteria would be sized to live nicely off the waste of those 6 fish (plus whatever you overfeed them).

When you transplanted plants, filter squeezings, and gravel, you brought a portion of that communnity over to the 29 but not enough to instantly support 14 fish. However, since you started with a decent sized colony, they should be able to reproduce relatively quickly to meet the higher demand.

I'd still keep a watchful eye for at least two weeks. testing every day, and be very careful not to overfeed while you let that colony build.
