Scale edge little curl out

[leo lim]

Observed that there is one scale on the 5th level the edge little curl out, maybe abt 0.2mm. What is the cause and treatment?

Water parameter readings?

NO3 : abt 35mg/l
PH : abt 6.3

Did not measure the ammonia.

Changed 30% water last Fri.

However, now looks like the "curl" gone....maybe it little white stuff on the edge that looks like curling.

It is always good to have ammonia and nitrite readings as well. Keep monitoring. Cheers.

Measured the NO3 and PH this morning, after 2 WC of 30% each in the past 1 week.

NO3 : Little better, abt 30mg/l
PH : 5-6

Not surprise the PH is low as there is no CC. Was told by bro to remove as Red prefer low PH. Do you think I need to add a bit of CC to bring the PH to 6-6.5?

However, one good thing is that the fish has resume eating bull frog, SW...after the feeding of cricket.

Yes, pls do it gradually.

f the edges is lifting up, it mean it's going to develop chip scales. Anyway, not all red will do well in lower ph. IMO, add CC to buffer the PH to 7.
