New to the Hobby... my pH does not stabilizes... everything else is okay.
Hello everyone, I am new to the Hobby...
my pH does not stabilizes for some reason. Ammonia is usually 0ppm and at times < 0.25ppm (less than) but reaching 0.25ppm. Nitrites are 0 Nitrates are 0 I have optimal filtration and clear water. just the pH is at issue. any suggestions to help keeping it stable? I have API Buffer, but I would like it to be stable. History: new tank running for about 2 weeks. I have Aragonite live sand and dry rock. |

The pH will fluctuate throughout the day, higher during the day and lower at night. The fluctuation is a by product of photosynthesis. The algae and corals remove CO2 from the water during the day, which uses up the carbonic acid in the water, and that causes the pH to rise a little. Then at night the algae and corals respire CO2 back into the water, which converts to carbonic acid and lowers the pH. The pH can move 0.2-0.4 pH units over the course of a day. As long as the pH is consistently in the 7.7-8.4 range you will be okay. Try to measure your pH at the same time of day every time to get around the daily fluctuation.
Many people run a reverse photoperiod in their sump to offset some of the fluctuation. The reverse photoperiod just means that they have the lights on for the algae in their sump at night so that those algae photosynthesis at night and use up the CO2 produced by the algae and corals in the display tank.

If you are still reading ammonia, then you are still in the early stages of the cycle, which will affect the pH. It's not really necessary to test pH during the cycle, because it will fluctuate quite a bit.
Did you introduce any sort of ammonia (ghost feeding or raw shrimp) to kick off the nitrogen cycle? I see you used dry rock. Adding something to jump start the cycle is usually best when using dry rock. For future reference - http://www.reefkeeping.com/issues/2004-05/rhf/index.htm If you haven't already done so, please read through all of the stickies at the top of this forum. To Reef Central

thanks guys for the responses.
I have a few fish in it for about 6 days now. They are very happy and the pH always at the same range and so is the ammonia less than 0.25ppm. Is this ammonia normal? or does it have to be flat zero. prior to adding fish the ammonia was 0 and pH remained the same like now. |

There should be no fish in the tank until your tank is fully cycled. Cycling with dry rock can take up to 6 weeks.

to reiterate
pH is not your main concern here.
Ammonia is

I would think that 0.0001 Ammonia is bad, but I read other posts if I am getting readings at < 0.25ppm that I should do nothing but wait few more days, re-test and see if dropped, remained, or increased, then I should do water change.
but I am no expert to decide whether this is true or a myth. |

Maybe I missed it somewhere, but what are the pH values you are seeing? How are you testing them? At 2 weeks old, pH isn't much of an issue. The process of cycling in a tank is going to cause some pH and alkalinity fluctuations. It is generally not time to start worrying with pH until the cycle is complete.

What kind of fish are in the tank? Some fish are hardier than others and can sometimes survive the cycling process.

Get the fish out of the tank into quarantine, which you desperately need anyway. Read the stickies.
