Hi, I am writing from Italy.
this is my first attempt to a controlled spawning so I am asking you a confirmation that I got right the full process:
1) I filled a 500 liter tub with 20 cm green water coming from the winter rain collected over my swimming pool cover to grow infusoria (PH 7 and KH 0). Then added other 20 cm with main pool water (PH 7,5 and KH 13) to raise KH.
2) I put daphnia magna in the tank (no areation so far)
3) I will put my selected koi set in an intex pool with areation, spawning ropes and no filtration
4) Once spawned I will put the spawning ropes in the tub (question: if i use malachite green and then put the ropes in the tanks the daphnia will be killed?)
5) Will add Sponge air filters to the tank
6) after 2 weeks I will raise the water level to 80 cm (fry swimming)
7) after other 2 weeks I will cull and put the selected fry in the main pool in a fry cage (main pool with daily complete water change and no filters)
Do you find it correct? Do you have suggestion?
Thanks a lot
Alberto
