last Sunday, i tested again the pH in my oscar community tank... wow...
it is already 3.5... but i have not seen any changes in my oscar's breathing..
considering that very low pH in fresh water is detrimental to adult fish health...
i do some experimentation again... gradually, it is now stabilizing @ 6.5..
hopefully, i can make it at 7.0 without any nitrite spike...

previously, i thought it was cause by old tank syndrome wherein i don't have frequent
water change and all my filters are old too... but this time, it happened when i have just done
the water change... and noticed my huge RTC refuse to eat... so i tested immediately all the water
and found out the pH is on 3.5 level, critical to adult fish inside.... nitrite and ammonia remains zero
while nitrate is at 15.... i dose the system with baking soda (1 tablespoon /200gal) and add rock salt
to avoid nitrite spike.... so this morning, i am reading pH=6.5 and no sign of stress among all my fish.

I honestly didn't think ph could even naturally drop that far. Maybe some chemical was added to your water? Glad your fish made it through.

i believe it can considering that i do not do water change for a long time....
remember, i have the aquaponics system of filtration wherein it took me 3 to 4 months
before water change,... all i do is topping the water to replace the loss due to evaporation....
more over, i keep using 5 year old filter media in my system... i seldom test my water too
since i am using all my fish as the indicator of my water quality...

that is why i immediately tested the water when my RTC did not come to meet me during
feeding time and my oscars are all staying at the corner where water from the tanks is dropping...
