fishless cycle update
got an update..here are my before and after tests..before wc....can it be im gonna finally finish soon..surely hope so
2 hours after wc..will check in the morning again.
high ph.......?(color was off the chart...like a deep yellow)
Is it bad if the pH doesn't change after a PWC? My pH has always been hovering around the same no matter what (desalinated tap water with conditioner in it) I noticed the CI finally went to 0 when I used Prime instead of another brand. I guess it just wasn't getting rid of enough
(My pH is always been 6.4 and 6.8 regardless of what I do)
I agree with Gwen....once your nitrosomonas and nitrobacter colonies are up to speed, you will rarely, if ever, measure any ammonia or nitrite. However, since you are measuring high(er) nitrates, it looks like your getting close (although I think it would typically take a very large water change to drop nitrates from 80ppm to 20ppm).
Due to buffering, pH tends to be very stable. Often folks that attempt to alter pH find it to be almost a loosing battle as pH tends to return to previous values. As I learned in my (truckloads) of composting days, pH often goes acidic during periods of organic matter decomposition, but returns towards neutral when complete.
What is the pH of your source (tap?) water?
@AbbeysDad... makes sense. I was using the fish meat/food cycling. So the rotting meat would have done that. The pH is pretty much the same, maybe slightly higher out of the tap.
I would expect your tank pH to be closer to your tap pH. Perhaps your water is soft and not providing much buffer? I'll defer to others here with more knowledge about managing pH.
However, a neutral (7.0) pH is considered very good for a community tank, so 6.8 isn't bad and would be perfect for most fish acclimated to it.
Most fish adapt very well to a very wide range in pH. HOWEVER, rapid changes in pH can spell disaster (Although not fish, I'm reminded of a disaster when I added some ground limestone to a worm bin).
The point is you are much better off living with your pH rather than adding things to try and change it. (Just my $,02)
