We have the pool for 10 years, and have now reshuffled it.
Due to an error of the CO 2 system, most fish are unfortunately died. ;-(
The cash pool is running only a week.
We have removed the entire aquarium, combined with new gravel and soil.
With the old pump, or the unwashed filter up again. Water zugeabe with 30 l Backwater, the rest with tap water and distilled water. Water was added.
AquaSafe pure Altpflanzen trimmed and clean
After one week the new Barben pure, and We'll see ;-)
I would be happy for your comments ;-)
