Hey mate. Where in Sydney are you. I am at zetland and the water out of the tap is
Ph 7.2
Gh 8
Kh 2
This is using API liquid tests. I found testing ph at 4 pm and using outside natural light gives me 7.2 on the colour chart. Inside it looks greater than 7.4. I tested using I high range test and got 7.2.
Back to the original question? Have any other fish displayed symptoms?

I'm from Blacktown. Tested my water last night & even it had a pH higher than 7.4. I bought a Sera pH kit which measures up to a pH of 9.0 as well as a gH test kit.

Looking that the water quality reports from Sydney Water, the pH levels in the latest report seem to match up with the readings I am getting using the pH test kit I do have, but will confirm with more accuracy with the new kit.

We had 15 neons, but removed & euthanised one, and at last count there were only 13 (that we could count).

Hope the tests went well. But as you are aware we draw our water from different catchments so that may explain the difference in Ph. The only thing i could suggest as ive read it somwhere on this forum is to add driftwood which will bring your Ph down a little. But im not too sure. Im still learning but if i was to offer any advice stay away fro chemicals that alter Ph. I defnately have read that while it provides a fix it will return to normal andcause even more stress.

Anyone feel free to correct me if im wrong.

Goodluck mate

I bought the Sera test kits for pH and gH and did a test for each of them.

pH was 7.5

gH was 10dGH (I think), will test again in a few hours.

When testing tap water for pH, remember to shake some of the tap water briskly for several moments to outgas the CO2 before testing. Depending how much CO2 is in the water, it will affect the pH test. Doesn't matter for GH, just pH.

Byron, having seen the information from our water supplier, what sort of value should I be looking for in terms of dGH.

I did the test but the change in colours from "red via brown to green" is very subtle. The red is more pinkish, and the green is rather light. Assuming those colours are correct I got a dGH of 9-10. Is that what I should be expecting? Or have I picked up a dud kit?

Is tghis the API GH kit, or the Sera? I've not used the Sera; the colours on my API GH kit are orange to green, and it took me a while to fathom the changes.

GH is at 3 dGH or close, so that is very soft. Looking at your fish list, this is perfect for the soft water fish which is everything except the platy, they will struggle. I would either return these, or separate them into another tank and increase the GH for them.

Plants should be fine, though 4 dGH is usually mentioned as the minimum. This is due to calcium, essential to plants. But rather than fuss over this now, I would leave the GH and see how things go. If the plants start to show signs of calcium deficiency, we can discuss options.

I'm using the Sera test kit, I worked out the colours and my tap shows 4dGH and the tank is about 5 or 6dGH.

pH from the Sera test kit is about 7.5

Phosphates are through the roof (5ppm), but no algae as I was expecting as nitrates are <10ppm
