i picked up a bottle of kent yesterday, i want to say off the top of my head its micro vert. it supposeouvly is for sponges,corals,anemones, and filter feeders. i got it to add some sort of food source to my water for a common neon green sponge i have growing in a few locations on my live rock and some tiny feather dusters, nothing else is in the tank yet.. i mean i see some copepods and some bristleworms ( nasty lookin critters huh? ) and whatever bacteria growing in my live sand but no clean up crew yet and no fish, so what would be benifitial to add to the water to get a more natural sea water? im not looking for chemicals im looking for food sources like plankton and whatever should be in the water..i want to seed the water now, so by the time i have fish and everything it has a good natural food source supply in the tank as well as my refugium which hopefully is completed in the next week or so. anyways any advice? thanks.
