What am I doing wrong?
Hello all! Hope you all had a great Christmas and everyone is going to have a great year ahead.
My question is "What am I doing wrong?"
I have a 300 litre tank that was setup about 7 weeks ago. It had 2 x 2217 eheim filters, one running a barry uv light and the other into a chiller set at 28 degrees. A 2215 filter is going into a dupla S reactor and the ph contoller is set a 7. Two T lamps are on for 5 hours in the evening.
Now, the problem is that the fish are "gasping", I have done a KH test and its ok at 5. The nitrate test is zero and the nitrata test is also good at 30ppm.
Ammonia is zero.
I have setup a timer to an air pump for night time to run for 3 hours to help the fish.
The dupla C02 plastic bubble shows also clear, meaning hi CO2.
The plants, which are mostly swords and some very small anubis are NOT pearling.
What's the problem? Please help as its driving me crazy!
