Question about Ammonia and Fish less Cycle

here are my readings for the last week:

Ammonia Nitrate Nitrite pH

Day 14 thursday February 19th 2015 1PPM 4PPM 5PPM+ 7.6 re dosed to 4 PPM Ammonia
Day 15 Friday February 20th 2015 1PPM 5PPM 5PPM+ 7.6 re dosed to 3-4 PPM ammonia
Day 16 Saturday February 21st 2015 0.5PPM 10PPM 5PPM+ 7.6 re dosed to 3-4 PPM ammonia
Day 17 Sunday February 22nd 2015 0.5PPM 10PPM 5PPM+ 7.6 re dosed to 3-4 PPM ammonia
Day 18 Monday February 23rd 2015 0.25PPM 10PPM 5PPM+ 7.6 re dosed to 3-4 PPM ammonia
Day 19 Tuesday February 24th 2015 0PPM 10PPM 5PPM+ 7.5 re dosed to 3-4 PPM ammonia (24 Hours apart) 8:50 am
Day 19 Tuesday February 24th 2015 0.25PPM 10PPM 5PPM+ 7.5 re dosed to 3-4 PPM ammonia (12 Hours apart) 9:20 PM


Tank has begun to show the ability to lower ammonia from 3PPM to 0PPM in approximately 12 Hours.


Day 20 Wednesday February 25th 2015 0PPM 10PPM 5PPM+ 7.5 redosed to 3-4 PPM ammonia (12 Hours apart) 9:20 aM


Bacteria has been oxidizing the ammonia into nitrite and the nitrate levels have slowly been rising but I have had to seriously increase my ammonia
doses to get to 3 PPM before it was 3-5 Drops per Gallon , now i'm having to dose at least 7-8 Drops per gallon to get that same reading. by the time it reaches 9:20 pm when i re analyse, it will have dropped back to 0PPM, the question is this , Why am I having to increase my ammonia dosage in order to see 3PPM ?

I am checking my water about 1 hour after dosage. I thought, maybe it's an inaccurate reading ? even if it were , my result are still back at 0ppm within 12 hours. Anyone have any idea's as to why this is happening ?

The bacteria that break down ammonia are becoming more plentiful, more effective at reducing ammonia. You're now waiting on the other bacteria to grow--the ones that break down nitrite to nitrate.

That is great to hear . so essentially there are so many of the Nitrosomonas bacteria that in order for the ammonia level to rise Im having to increase the amount of ammonia by a lot in order for those guys to even break a sweat.

This is incredible . I love science.
