Hi Mark & Khoo,
How to build a bio-filter?
Thanks for the advice. Can I know what should I put in the fibre glass filter. As I am currently using the outlet from the Ehiem cannister for my fountain, how can I achieve that with the fibre glass filter.
I visited a koi dealer yesterday and he advice me to change 10-20% of the water to reduce the nitrate level. He also ask me to but AquaMed Bacteria for the pond and gave me some PH buffer (can someone tell me more about this).
After the water change, I did a test on the PH and it read as below 7.9. Does the water change help.
My pond detail is as follows:
Size : 2m x 1m x 0.5m (approx)
Water level : 2m x 1m x 0.3m (approx)
mountain : 2m tall
koi : 5 (avg 10 - 15 cm)
filter media : 1st layer = volcano rock
2nd layer = green sponge
3rd layer = plastic mat
Thanks. I have only start rearing koi about 2 weeks ago so I need lots of guidance.
Does anyone know where can I seek guidance in Singapore on rearing koi?
