Thanks for the quick replies. I am beginning to wonder if its water flow that could be the problem. I have done a number of water tests and these are the results:
- SG 1.024
- PH 8.4
- Ammonia 0.25
- Nitrite 0.1/0.2
- Nitrate 10
- Alk Normal
- Temperature 78f
Any more suggestions would be great.
Cheers
