Water parameters of Borneo Sucker (Gastromyzon sp.) habitat

Okay, in addition to the moss collecting trip, I also brought along some simple test kit to measure the water parameters of Borneo Suckers (Gastromyson sp.) natural habitat. The idea to measure the water parameters was a result by interested parties around the world requesting for more infos about this suckers. So here it is...

Some waterfall at upstream...people use to come here for picnic

For the image above, the parameters are:
Temperature: 24.8°C
pH: 7.5
Hardness: 3°dKH (approx. 54 ppm KH)
Sampling time: 1.00 pm

The spot I used to catch this suckers about 1km downstream from the spot above

For the image above, the parameters are:
Temperature: 25.7°C
pH: 7.5
Hardness: 2°dKH (approx. 36 ppm KH)
Sampling time: 2.30 pm

But as a warning, I’m limited to only three of this water parameters...and if in any case, if you find that the infos are not enough or inaccurate please give me a comment, and I’ll try to work things out.
