Am I Cycling Please

Yay.......    

Thank you very much Sandra

Your falling KH and pH - do you have any bicarbonate of soda in the kitchen cupboard? If not, it is sold in the home baking section at the supermarket (small plastic tub)
You need to add some to your tank, dissolve in a bit of water first.
If I remember, the tank is mid 20s litres? Use half a teaspoon (half a 5 ml spoon) and see what that gives you after waiting half an hour for it to mix in. You can add more if necessary. Aim for a KH around 10. The pH should go up as well, it doesn't matter how high as the filter bacteria prefer it high to multiply. At this stage the main thing is to stop it falling.

After changing the water on Saturday you had 1.0+/0.5 and 2 days later they were zero. So you do have bacteria, just not enough.
I would continue testing every 2 days and adding a 1ppm dose when ammonia drops to zero. As soon as you have zero ammonia and very low nitrite, then add a 3ppm dose and test next day.
The filter bacteria do need carbonate as well as ammonia/nitrite to multiply. Hopefully adding bicarb will give them a boost.

The big water change after the cycle has finished will remove all the sodium so it is safe to use bicarb during cycling.

You don't mean to say there is someone older than me  I though I was just about the oldest at 61 

I like maths  One of my favourite subjects at school. I had to choose between maths and biology at A level and biology won.


Strictly speaking, you add 3ppm ammonia then wait until you get ammonia under 0.75 and nitrite over 2. You are past this stage.
Then you another 3ppm ammonia and test every 2 days till you get 2 sets of readings where ammonia is zero, that is zero one day and zero again 2 days later. You have reached this stage - 0.2 on 25th, 0 on 27th and 0 on 28th.
Once you get the two zero ammonias, you add 1ppm ammonia, which you did on 28th, and still test every 2 days.
The next stage is waiting till ammonia drops below 0.25 and nitrite below 1.0 which you had on 30th. At this stage you add 3ppm ammonia, which you did, and test after 24 hours.
If you had double zeros after this 24 hours you would have been cycled, but you didn't, you had amm 2.0 and nit 1.0 on 31st. So you are supposed to continue testing every day till you get amm less than 0.25 and nit less than 1.0 again - only you did a water change.

Today, 2nd Feb, you are under amm 0.25 and nit 1.0.
Thinking about it, add a 3ppm dose of ammonia and test again tomorrow. *If you have double zeros, good. If not, test every day and wait till you have amm less than 0.25 and nit less than 1. When you get those readings, add 3ppm dose ammonia and test again next day. * Repeat from * to * until you do get double zeros 24 hours after adding a 3ppm dose.

Once you get to double zeros 24 hours after adding a 3ppm dose, you will be cycled.
