How Much Is This Going To Effect My Cycling?

[-Jo-]

I am curtrently away from home and will be back on sunday after noon where I am goingn to do a massive water change, add my plants and get some fish on the monday as my tank has finally completed its cycle. wooo!

My sister is adding ammonia to the tank - but this morning the PH leve has dropped dramatically. I live in an area where the water is very soft, so throughout my cycling I have had problems with fluctuations in PH. It has dropped from 6.8 - 6.0 in 2 days.

Is this going to effect my tank significantly? I will be home on sunday for a massive water change - but just was just wandering if in the mean time its going to effect the cycling? I am done - but can this 'un-do' it or anything like that?

On theory, Ph below 6.5 starts to inhibit the nitrifying bacteria and at 6.0.
However, since you are only going away for a few days before you fix the problem the effects may not be adverse.

What I would worry in your case is that your Ph seems very unstable and the same may happen when you have the fish in.
What nitrAte levels are you measuring at the moment and how much ammonia per day have you redosed?

My nitrates are very high which will be lowered with my water change on sunday. When ammonia hits 0ppm I redose with 6 drops of ammonia to bring it up to 1.0ppm. but at the moment its haning on 0.25ppm - im guessing due to the cycling being stalled by my dropin PH and big amount of nitrates.
