i think its not the media.. i encounter this problem before using different media...

i post that thread on the stingray forum..

i fell frustrated so i reset my tank using new media, suspecting that it might be the media that cause my ph to rise... but here it goes again.. the same problem

there should be something wrong with my water... but i dont know

our water system at home has a water softener for the whole house... and pass by a carbon filter before it goes to a hose for my water change...

all my other tanks are ok with some arowanas on it..

only this tank with some rays previously occupying it has a problem...

does water softener cause it?
or the carbon filter?

but i have lots of friend hobbyist using it also and all of them are fine...

Hmm.. putting pH aside for awhile, how are the occupants doing? Are they eating well and not exhibiting unusual behaviour? What are your other parameters?

As long as it's stable, I personally feel that it's no issue. Fluctuations kill. Also lower pH kills off your BB.

The increase in PH got to do with aeration, which is different in each tank/filtration system.
It is also related to pump flow rate & any air stones setup in the tank that increase tank aeration, thus increasing O2 & reduction of CO2.
I would think you have a good filtration system that also help to maintain high O2.

● Aeration - Increasing the oxygen concentration in your water will serve to drive down the carbon dioxide concentration. As discussed above, less carbon dioxide translates to a higher pH. Therefore, you can increase the aeration in the tank to raise the pH.

Tank filled up with AC, no pump running since last week.

15/04 @ 0030hrs on pump and added BB
15/04 @ 1500hrs on of hydra stream
15/04 @ 1530hrs added TFB
15/04 @ 2130hrs took test.
PH 7.4
Ammonia 0.25ppm
Nitrite 5.0ppm
Nitrate 10ppm

Noob here, are the readings acceptable? Will it be ok to let tank to cycle for a week then add in aro?

Fish-less cycle is tricky and often unsuccessful. You need some level of bioload to trigger the nitrogen cycle.

Effective hack is to use donor biofiltration material/media from matured tanks.

Been doing it all this time.

Just make sure the filtration is same type.
Had bad experience using donor from submerged sump media in a new OHF FILTER, the ohf was aerobic filtration fast flowing water while sump is more anaerobic gentler flowing water.
