Hi,

You spoke about dried phyto last day (ESV).

What do you think about marine snow ?

What about Marc Weiss product ? Coral vital and LSB coral vital which are created for helping sandbed ? We can imagine that when we are patient, there is no need of such product

... or after a move ? or during some problems ...

Hi Manu,

What do you think about marine snow ?

Natural Marine Snow is a particulate mixture of mucus and various microalgae and detritus. It is effectively impossible to duplicate in aquaria.

The aquarium product called "Marine Snow" is over 99% water, and has effectively no caloric content. Used in its recommended dosage, it - fortunately - will not harm anything in the tank, however it doesn't contain enough nutrition to feed anything.

I did a study last year where I had an analytical chemistry laboratory examine 15 different foods and additives and determine the contents. The results are listed here (the text is in English, but the tables which present the data should be under standable).

The URL: http://www.animalnetwork.com/fish/data/foods.asp

You may use these data to make your own conclusions about "Marine Snow." Dr. Rob Toonen did a feeding study trying to raise some rotifers and some invertebrate on it, and found that it provided the nutritional equivalent of filtered seawater.

What about Marc Weiss product ? Coral vital and LSB coral vital which are created for helping sandbed ?

These products are probably better. Coral vital, gram for gram, is about as nutritious as frozen brine shrimp. I don't know about LSB, but I think Weiss tries to make a good product.

We can imagine that when we are patient, there is no need of such product ... or after a move ? or during some problems ...

I don't think there is ever any need for a product as dilute as "Marine Snow." I can't feature it being good for anything. The other products may have some value.

If your tank is well fed to begin with, the utility of such products is questionable.

Cheers, Ron

Do you authorise me to translate it to put on this site, Ron?
