Hi Bill
Thank you for your indepth reply - I do siphon and I also was not aware of those vacuum things.
I am careful with the temp of water change water and have tested my water before it goes in and no phosphates etc in water.
Readings last night were:
Ammo 3.7
Nitrite .50-1
Nitrate 10
PH 7.6
I don't know about the hardness of the water - how do I test that please?
I did a 25% water change after doing the tests.
There are small haps in there and they seem to be coping - showing no signs of stress now and eating normally. Colours remain the same now as when they were stressed they would change colour.
Hope I have covered your questions.
Thanks
Arly
The only thing I have put in the tank apart from Ammo-Lock twice is Stress-Syme on day 1 and day 7.
There are rocks,gravel and plants in the tank.
The rocks were from an existing tank,but the gravel was new.
I am running a Whisper Second Nature Bio Filter and a small internal power filter - carbon in the Whisper.
