Bacteria question

Does anyone know on average how long it takes once a tank ornament is in a fully cycled tank does it take to build a nice bacterial colony on it that can help can help to cycle another tank?

Generally we let items seed for around 2 weeks to grow the bacteria on it.

sweet The 10 inch pleco just got picked up for his new home so now i need to repair the cycle on that 10 gallon tank. I did a nice water change to get the ammonia to about .50 - 1 ppm and i have a Large tank ornament that has been in the 20 gallon cycled tank for like a month so it should help it along to recovering that cycle

(Edit) I also just thought about it and put some Stress Zyme+ in both tanks so that any bacteria that might be lost from moving that big ornament out with the 20 gallon and a kick start to the 10 gallon

Simply removing the fish will "repair" the cycle. The problem is that your filtration is not capable of handling the bioload. They are still working, as hard as they can. You just can't tell because the pleco creates THAT MUCH waste.

Assuming you have a filter on the 20, and are not ridiculously overstocked like the 10 inch pleco in a 10, the bacteria colony in the filter will pick up the slack. You really shouldn't even see an impact from moving it.

Sounds like it was for the best! He really need more space than a 10 gallon. Good for you for moving him.

Kinda concerned I now have a ammonia source. I know this isn't the most recommended way of cycling my fishless cycle has turned into a fish in cycle because my moms roommate got a betta and was going to use this like 1 gallon bowl that has a stand. The bowl had no way to regulate the temp so it was flopping to like 55 degrees and the betta was becoming lethargic from the temp in the bowl. Not only that but they don't have a testing kit yet and i tested the water and it was at around 6 or 7 ppm of ammonia after a few days. So I cleaned out all the food i put in the tank to let it decay and produce an ammonia source and did a water change. Well the betta has been in there for a few days and i still have no Nitrites or Nitrates I am thinking that the Pleco while in there did truly hurt the bacteria that were in there and not must overwhelm them. So if i was seeing nitrites before the pleco then does anyone know how long it will take to see them again? Do you guys think that i should just dose it with Stress Zyme+ get some quick start or just leave it and see what happens.

(Edit) Thought i would ask, if before when the pleco was in there if the bacteria was trying to work to brake things down shouldn't i be be seeing like Ammonia Nitrites and Nitrates or a mix of them instead of just ammonia?? I mean yeah lets say the Nitrifying bacteria wasn't able to keep up I would think i would atleast have a somewhat cycled tank not one that isn't cycled at all.

I am so glad to hear that you re-homed the pleco. Good work.

Ultimately you should see 0 ammonia 0 nitrItes and <20 nitrAtes. At least I don't let mine go over 20.

It shouldn't be long for it to kick in and all even out. If you have it I would use AmmoLock or Prime to detoxify ammonia which will make it less toxic to fish but keep it available for the bacteria. If you still have a lot of ammonia after a wear change, I'd test your tap water.

What kind of test kits are you using? An "ornament" won't get enough bacteria on it to start a cycle. A filter pad would, but not an ornament.

I agree that an ornament won't have enough BB to cycle a tank. I think that your colony is so strong from the pleco it's handling your bettas waste with no issue. I have a 10 gallon with a betta, a DG, 5 cherry barbs, a red tail shark, 2 otos, 3 platies, 3 shrimp (and multiple babies), a nerite and baby platies and haven't seen any readings in the 3 months it's been set up. All I'm running is the filter that came with the 10.
