Yeah, ok, but does it maintain temperature and flow?
When using Steady Chem there is no need to worry about either!
The corals will be so healthy that they can resist any temperature a human could survive! I hear, from the voices in my head, that the government of Australia is planning to bolus dose the entire great barrier reef with it the next time a mass bleaching event begins.
As for flow, the corals will have such fantastic polyp extension that they'll create their own flow just by waving their tentacles around! Beware though, adding this to pulsing Xenia may cause such a large wave to form in your tank that is may bust the tank seams. I'm pretty such this is what happened in a number of those Red Sea reefer front glass failures.
