Too much ammonia #1
Been following the instructions of the cycling article

3) The following day use the ammonia test kit to measure the ammonia in the tank.If it’s below 3ppm (parts per million) use the ammonia calculator below to calculate how much ammonia to add to bring the level back to 3ppm. It may take several days before you see a significant drop.
4) Repeat step 3 every day. This process is to start the cycle off (the initial bacterial growth) and keep the bacteria alive by feeding them ammonia at the correct concentrations in the tank water.
5) After about a week you can start to test for nitrite in the water. Ammonia is converted to Nitrite in the first part of the cycle so when you can detect it, it means the cycle has started.
6) Continue testing for ammonia every day. Whenever it drops below 3ppm add enough ammonia to bring the level back up to 3ppm using the calculator to obtain the correct dose. Also test for nitrite every other day. You should see nitrite rise and then start falling after a few weeks

got a healthy ammonia reading of between 3/4ppm and yesterday nitrite was at a reading of 4.

Reading other posts there is conflicting information as to whether to follow the above instructions and every time the ammonia drops below the 3ppm to top it up whereas other posts have said don't top up until the ammonia goes down to 0.

feeling rather confused.

Re: Too much ammonia #2
Either will work - personally I let it drop to close to 0 before topping up.

Re: Too much ammonia #3
Done another test tonight. Ammonia reading at 3 but nitrite has increased to 8.

I’ve had a my delivery of Dr Tim’s once and only which says reduces ammonia & nitrite naturally whilst adding the good bacteria.

Worth just adding this or do you think best to do a partial water change then add it??

Re: Too much ammonia #4
You can add it, but don't do a water change as you need the ammonia for the bacteria to feed on.
