I have a question about PH. My PH has drop constanly even tho i buffered it up with seachem ph buffer and i buffering it almost everyday my PH still dropping. Now it read 7.59 during night and 7.8 during day. But i've been stop use PH buffer for 2 days because my ALK jump from 8 to 12 DKH
Thanks
I'll be honest that may come from many things. I took this little paragraph from a site and informational and I think it can help you.
Low pH problems are those where the pH is below about 7.8. That is, where the daily pH low drops below 7.8 for any portion of the day. Of course, if the pH reaches a low value of pH 7.9, aquarists may still want to raise it, but the need is not so immediate. Several things can commonly result in low pH, and the solution to each of them is different. Finally, there's nothing to prevent a tank from having all of these problems simultaneously!
The first step in solving a low pH problem is to determine why it exists in the first place. Some possibilities include:
A calcium carbonate/carbon dioxide reactor (CaCO3/CO2 reactor) is in use on the aquarium.
The aquarium has low alkalinity.
The aquarium has more CO2 in it than the surrounding air due to inadequate aeration. Don't be fooled into thinking that an aquarium must have adequate aeration because its water is very turbulent. Equilibrating carbon dioxide is MUCH harder than simply providing adequate oxygen. There would be NO change in the pH between day and night if equilibration of carbon dioxide were perfect. Since most aquaria have lower pH during the night, they also are demonstrating less than complete aeration.
The aquarium has excess CO2 in it because the air in the home that it is being equilibrated with contains excess CO2.
The aquarium is still cycling, and has excess acid being produced from the nitrogen cycle and degradation of organics to CO2.
if you don't have AC or a chiller you're both gonna fry lol
