Thank you, Claude!
Were Artemia nauplii and copepods live, bottled or dried, what size of copepods?
What amount of food for a day (approximately)? Fed once a day or more frequently?
What filtration 40L tanks had, that was efficient enough to keep nutrients low and water - without yellow shade?
Small skimmer - which one?
You see, I tried 5 different skimmers, including Tunze Nano DOC and Turboflotor 1000, and they didn't clean water enough.
I have one tank with clean water and can move one of the chili corals there, but after starting feeding it the water quality will drop within.
Also, this tank has relatively low flow, 15x tank volume per hour. I'm afraid this will be not enough.
What amount of flow was sufficient in your experiments?
How was set pattern of flow in these 40L tanks?
Did you try to keep chili coral in tanks without ozone?
Sorry for asking so many questions, I'm trying to get the whole picture of the factors involved.
I already ordered one more small skimmer, and as soon as I'll receive it I may set a personal pico tank for chili corals.
