The plants should be fine as they will use the ammonia as food.
Just remember to use the ammonia calculator Big Grin

Hi Paul,

Some people do have plants in their tank when starting the tank cycle. I don't go for that approach and I'll explain why. The whole point of cyclng a tank is to set up and establish a biological filter. And that requires ammonia and the right bacteria. That's the simplified version. The problem with introducing plants at the beginning of the cycle is that the plants may use up the ammonia leaving little for the bacteria to multiply in numbers. I assume you don't have any fish in your tank at this stage otherwise there is little chance of them surviving.

The stage at which to add live plants is at the end when ammonia and nitrite are unmeasurably low and nitrate is on the rise. The plants will keep nitrate under control if you get the balance right.

Good luck!

@LexIcon 

I wonder if you'd be interested in having a shuftie at something  that I did in Another Place, many moons ago! Somewhere buried in that nonsense should be bits that may interest you (I haven't re-read the thread to identify exactly where).

Do plants respond to a surge in ammonia at the same rate, or perhaps faster, than oxidising microblighters?

Spoiler:


If so, then I guess that would tend to support your approach I think.

Hi Vale!

Thanks for your reply.

I had a good shuftie at your post on TFFUK. I am also a member of that community but haven't been on there for ages. I knew when I very recently registered with Aquarium Forums UK that your User Name was familiar to me. Anyway, to business!

I guess the crux of what we're talking about here is, as you say above, "Do plants respond to a surge in ammonia at the same rate, or perhaps faster, than oxidising microblighters?". As your excellent work demonstrates (and contrary to popular understanding), Nitrosomonas can work very rapidly - from 1mg/l to 0mg/l TAN in just one hour!! So, what we now need is a figure for the rate of TAN usage by aquarium plants. I guess it wouldn't be too difficult (!) to devise an experiment to test this but, as I don't have the time, I'll contact someone that might know the answer. Will report back.

Too much overthinking going on here.

It's entirely down to personal choice whether you have plants while cycling or not. I definitely would as it allows time for the plants to establish themselves. Time for any rearranging to be done. And probably most important of all... Somethin "alive" to enjoy and watch develop, even if it's largely static while waiting for the day to arrive.

Hi Toeknee,

I respect your opinion but I don't agree with it. Having said that, you're obviously not alone judging by the additional posts above. I think there is some misunderstanding going on here. So, give me a second chance to clarify things.

When someone sets up a biological filter, they are often keen to do this as quickly as possible. So, if the plants consume ammonia at a rate faster than the bacteria can get their little mitts on the stuff, then it may take a very long time for the biological filter to become fully established. Therefore, if you have the choice, it is more logical to add plants at the end of the cycle - rather than at the beginning. That's all there is to it.
