Problem im facing with my tank

[nasty12]

i have a 1.5 ft Shrimp tank with 4 white cloud mountain minnow, 3 yellow shrimps, 8 x crs, 3 sakura, 3 orange shrimps.
But the water perimeters seemed weird...
Nitrate- 0
ammonia - 0.3 mg
Ph 5.8 (yesterdays reading was 6.5)

o.O any advise?

do you have CO2 running? CO2 lowers the pH.

how long has the tank been running? did any inhabitant die? If its a new tank it might not have been properly cycled yet.

Derk
PH drops has nothing to do with inhabitant dying or whether the tank is properly cycled.

N12,
Didnt see your post on KH ?

[nasty12]

hmm i dont have the kh tester..
i heard that it was perhaps due to the ada soil im using.(its ph6)
thus i did a water change hope all goes well=D

yes ada soil have PH buffering capabilities. So no worries, but low PH is causing some shell erosion on some of my nerite snails shells, so i will be using sechem prime + equilibrium this weekend for water change.
