Thats some corals, not all that are in the reef hobby (many corals are collected pretty deep that are in the hobby) and I was saying with a good system and nice corals like that why risk the swing when a 50% is probably all that is needed if not less?Well in the video it says they have been doing it since 2012 and that tank is fantastic so they are doing something right.
In the wild lots of corals are exposed to the air for hours on end at low tide and it doesnt harm them, they excrete a mucus film which protects them.
I guess I am asking if its the only option due to the fact the owner doesnt want weekly service or if its just something they were testing. The tank looked relatively clean and since its old I would feel like biological filters in the sand/rocks/water would reduce the need for such drastic changes.
Do they also not dose at all?
