Bioluminescent Dinoflagellates

[memnoch]

Sammy is correct in his thinking. Some species of dinoflagellates produce toxins that are filtered out of seawater by oysters. For this reason there are certain times of year when oysters are not taken from Galveston bay. I personally know of one person who ate "tainted" oysters who succumbed to a particularly bad affliction of hepatitis. I think i would be wary of putting these in your tank unless you are certain they are harmless. Remember that out in the ocean fish can swim away if they don't like the water conditions, not so in our tanks. Just my opinion.

you could set up a 10 gal for barely no money. the water could come from a water change out of your good tank and who needs dsb when just trying!! filters are cheap. just a thought robby
