Hi All,
I have had my rio 180 for approx 2 months now and have just got all my water chemistry down to the correct levels
PH 7.2
Ammonia 0
Nitrite 0
Nitrate 20
Hardness 14
I now do a 20 percent water change weekly and all seems well, but I seem to have a very slight foggy issue, I have just started to put a hardness cushion in to try and bring the hardness down a bit but can not explain what is going on, I would appreicate any help or advice you can give me.
The fish I have are
6 zebra Danio
1 Leopard Danio
5 Platys
5 Male Guppies
For the record I also have a air pump and stone installed.
After i installed the hardness cushion for a couple of days it seemed to be getting better, after a couple of days without the cushion it seems to have got worse. Help.
