Why do you do that and what’s in the tank?I remember dissolving a whole package of yeast in my tank long time ago, had a milky tank for a day or two, then it had dissapeared ( 600 liter tank with two Eheim cannisters). Not sure what i wanted to achieve anymore ( it was 1990 or so) but i can't remember any effects, pro or con
I know why. Reef tanks thrive on live sand. Vodka provides a carbon source for denitrificaion.Even dosing alcohol doesn't do much harm.. I red it is a popular custom in the reef community to ad a dose of Vodka to the tank.. I forgot what it is for, but some do.
I don't think they will eat yeast, if there are sugars available the yeast will proliferate and potentially remove oxygen from the water column. I used to use yeast for my Daphnia cultures, but it is always boom and bust.Will dwarf shrimp eat yeast. If not, will left over yeast turn tank water into alcohol.
May do, it would be down to amount of yeast.or be eaten by micros starting a food chain shrimp is on top.
It is like Marcel (@zozo) says they sieve particles, of a certain size, from the water column. They don't select, it is purely a size thing. Paprika and gram flour works quite well as Daphnia feed.Now Daphnia as planktonic crustacean live off zooplanktons like single cell algae floating in the water. Or as alternative food source the single yeast cell.
It does.Vodka provides a carbon source for denitrificaion.
I can't see any advantage either.Like all things it is about dose and amount of exposure but I think caution should be applied before adding ethanol to any tank!
