On the other hand, yoghurt seems to work very well for some sponges as well.
Keep in mind that most yoghurts have a lower pH than seawater, so you could consider adding a bit of CaOH to compensate for the drop in pH.

I understand these large feeding byopolimers like gelatine could be alginate too...
I assume we are talking about a product used in the Fauna Marin known as Ultrapac which is like artificial "mucus"...
I assume Ultrapac, Gelatine or alginate are the same and they have the same use and effects...
Am I right jptenklooster?
If I use gelatine or alginate can I have the same results than Ultrapac?

I don't know what the TM Reef Actif is made of (sodium alginate?) but you can easily make gel like food with it

That is my asumption my friend tatu...
That Ultrapac, alginate or gelatine have the same use and effects in feeding.

[jptenklooster]

I have used ultrapac as well and that is giving a similar growth as gelatin. I think ultrapac is gelatin, it looks the same, tasts the same and behaves the samme with respect to forming a gel in water.

Where you buy gelatin/sodium alginate ?
Can that be buyed locally in drugstore or local shops? Is that ordinary gelatin for home food ?

BTW in case you are not already read this article, here is nice new information about sponges and bacteria : http://glassbox-design.com/2009/spon...n-on-the-reef/
From Holland researcher Dr. Jasper de Goeij

Gelatin is just gelatin; it will be in the grocery store either in the baking aisle or the Jello section--Knox brand is the usual one, which is just plain gelatin. alginate is going to be harder to find, either you can go with a chemical company source or a food source: here's a place you can order it online http://www.willpowder.net/sodiumAlginate.html

Thank you Spracklcat.
So basicaly Ultrapac, reef actif and similar bio polymers selled in aquaindustry are just the gelatin or sodium alginate? Did they have more ingredients or that is just the gelatin/sodium alginate? Reason for asking is that I wont to made my own food for corals/sponges.

[Spracklcat]

I have no idea what is in those products (would be interesting to know) but I'd go with a gelatin food over alginate simply because it is easier to make and store.

[tatuvaaj]

Reef Actif might be something different, I was just guessing

[bluereefs]

So if I decide to use gelatin as aquarium food what will be best way to use him, only gelatin alone or mixing with some other ingredients? With cyclop eeze for example, vitamins, blendered sea products (fishes,shrimps,shells..), yoghurt .
How some of you use gelatin, how much, how often... ?
Do you think he will be good for sps,lps corals as well or only for sponges or non photosysntetic soft corals?

Any negative efect noticed?

[bluereefs]

Would like to see efects of home made food with gelatin and other ingredients mentioned in this great thread on my Trikentrion flabeliforme.



This is my favorite invertebrate in my tank, so far (aprox 3 months) she live quite nice without special food besides regular granular/flake food and frozen/dry cyclop eeze, but it will be interesting to find will gellatin, yoghurt ..etc made she even better.
